Three friends of different age and height stand in a queue for a photograph. The
photographer asks the youngest to stand to the right of Adam. The tallest stands in the
extreme left. Barry does not stand in the center and he is not the youngest. Donald is not in
the center too. All are facing the photographer. No person receives the same rank when put
in the increasing order of both age and height. Now, who is the shortest?

Answers

We can conclude that Donald is the shortest friend.

Who is the shortest?

This is a logical question, first, we know that the tallest friend will be on the left side, so we assume that the left position can be discarded, so we need to find who is in the right position.

Barry is not in the center and is not the youngest, so Barry is the tallest friend.

Donald is not in the center, and we know that the youngest must be on the right of Adam. So the only position left for Donald is the right one.

Then, we can conclude that Adam must be on the center and Donald on the right extreme. Then Donald is the youngest and shortest friend.

what are three characteristics All probability distributions have

Answers

Here are three characteristics that all probability distributions have:

The total probability is always equal to 1: This means that the probability distribution must cover all possible outcomes, and the sum of the probabilities for all possible outcomes must add up to 1. In other words, the probability distribution represents all possible events and the total probability of all those events is equal to 1.

Probabilities are non-negative: All probabilities in a probability distribution must be non-negative, meaning they can't be negative numbers. Probabilities must be greater than or equal to zero and less than or equal to one.

The probability distribution can be continuous or discrete: A probability distribution can be either continuous or discrete. A discrete probability distribution is one where the random variable can only take on certain specific values, while a continuous probability distribution is one where the random variable can take on any value within a certain range. Regardless of whether the distribution is continuous or discrete, it must satisfy the first two characteristics mentioned above.

These characteristics are fundamental to all probability distributions, and they help ensure that probability distributions are consistent and meaningful in representing real-world events and outcomes.

A 5-month-old child is admitted to the hospital with recurring respiratory infections. A possible cause of this condition is:. Bug WatcherMike had all the right tools for his job: the high-powered binoculars, the tripod with feet that bent in multiple directions so he could set it on rough terrain and the best darned camera available on the market, with zoom lenses that could make a fly 100 feet away look huge. Not to mention the clothesmicrofiber, breathable, comfortable, unscratchable by any branches known to man, and mudproof to boot. Oh, and he had good boots toodurable ones. So, when he caught sight of the most glorious luna moth any bug scientist could ever hope to spot, he was ready to shoot.The camera's shutter clicked 20 times before that luna moth had a chance to flap its front wing. This way, Mike made sure he had the kind of shot that his magazine employers would want. Then, as the moth hopped from one leaf to another, he used his rapid-fire shutter gizmo to catch it in motion another 20 times or so.But Mike could see something odd about this new leaf the moth had chosen. It had bumps on it he didn't usually see on that kind of leaf. And the moth started touching one of its feelers to different bumps in a weird way. It looked as if it were typing notes onto thebumps! Kind of a one-feeler-tip typing system, but it was pretty fast. And, between spurts of tapping the bumps, the moth looked right at Mike. Mike knew that a bug like this couldn't really see him. It couldn't make sense of a shape like he or his camera and tripod would form. But he felt that the luna moth was studying him, as if it were a people scientist.He missed a few shots as he paused in amazement at this idea. Then he remembered to catch the glorious moth as it moved. Maybe when he developed them, the photographs would help him decide if he was going crazy and imagining things.They didn't really. They showed the image of a luna moth twitching its feeler on the leaf. You couldn't tell why it might have been doing that. But, what if those odd bumps on that leaf really could tell some kind of story about him or about whatever that moth could see in his direction?1Select the correct answer.Here is a question from the text aids: Does Mike take good pictures of the luna moth?A. No. The equipment is not good enough to photograph it.B. Probably, but his fancy equipment doesn't work very well that day.C.
