If A and B are events with P(A)=0.7, P(A OR B)=0.77, and P(A AND B)=0.13, find P(B).
Answers
Answer:
P(B) = 0.20
Step-by-step explanation:
For these events, which are not independent or mutually exclusive, the relation between the various probabilities is ...
P(A or B) = P(A) +P(B) -P(A and B)
Solving for P(B), we find ...
P(B) = P(A or B) +P(A and B) -P(A)
P(B) = 0.77 +0.13 -0.7 = 0.20
The probability of B is 0.20.
__
Additional comment
The formula applies to independent and mutually exclusive events, as well. For independent events, P(A and B) = P(A)·P(B). For mutually exclusive events, P(A and B) = 0.

Can the sides of a triangle have lengths 16, 9, and 7?
Answers
Solution:
We know that:
Given side lengths of triangle: 16 units, 9 units, and 7 unitsThe sum of two sides must be greater than the third.Verification:
Let's verify the side lengths of the triangle.
=> 16 + 9 > 7 => 25 > 7 (True)=> 16 + 7 > 9 => 23 > 9 (True)=> 9 + 7 > 16 => 16 > 16 (False)Conclusion:
The following side lengths cannot be a triangle.
The rule is
Sum of any two sides must be greater than the third side
16+9=25>77+16=23>97+9=16They can't be a triangle

7. What is P(xs 93)?
O A. 0.16
O B. 0.975
O C. 0.84
O D. 0.025
Answers
The probability of (xs 93) is 0.975, the correct option is B.
What is the probability?
Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
We are given that;
Mean= 79
Now,
According to 1, 2, and 3, a normal distribution calculator can be used to find the probability of a value being higher or lower than a given data point x, given the mean and standard deviation of the distribution.
Using any of these calculators, we can enter the following values:
Mean = 79 Standard deviation = 7 Below = 93
The calculator will then compute the area under the normal curve that is below 93. This is equivalent to finding P(x ≤ 93).
P(x ≤ 93) = 0.975
Therefore, the probability will be 0.975

Alfredo's painting his storage shed. He won't paint the top or bottom of the shed so he needs to calculate the lateral surface area of the shed in order to know how much paint to buy. The shed is in the shape of a rectangular prism as shown below what is the lateral surface area of the storage shed
Answers
Answer:
He is not painting the bottom or top meaning that he will paint 4 sides total, when there is a rectangular prism there are 6 sides and 3 pairs of 2 equal sides, so since there is a wall that is 9ft x 7 ft there is two of those, and since there is a wall that is 12 ft x 7 ft there are two of those as well. meaning that (7x9)·2=126 and (12x7)·2=168 when added we get 294. meaning that he needs to paint an area of 294 ft

Freddy wants to buy a bicycle.
He can either make 12 payments of $88 or a single payment of $780.
How much money will he saved if he buys the bike in a single payment
Answers
Answer:
$276
Step-by-step explanation:
in h.p he would pay 12*88= 1056
amount saved = 1056-780= 276
Freddy would save $276 if he buys the bike in a single payment instead of making 12 monthly payments of $88.
To calculate how much money Freddy will save by buying the bike in a single payment, we need to compare the total amount he would pay in each scenario.
If he makes 12 payments of $88, the total amount paid over the 12 months would be:
Total amount = 12 payments × $88 = $1056
If he makes a single payment of $780, that would be the total amount paid.
To calculate the savings, we subtract the total amount of the single payment from the total amount of the monthly payments:
Savings = Total amount of monthly payments - Total amount of single payment
Savings = $1056 - $780
Savings = $276
