Answer:

Randomly generate an integer from 1 to 7 two times, and the probability is 1/7 ^2

This is the statement that best describes the use of a simulation to predict the probability that two randomly chosen people will both have their birthdays on a Monday.

There are 7 days in a week, so there are 7 choices but only 1 Monday. So, 1/7 is the probability that a person's birthday falls on a Monday.

1st person asked will have 1/7 probability.

2nd person asked will also have 1/7 probability

So, (1/7)² is the probability that both persons will have their birthdays on a Monday.

Answer:

the answer is D

Step-by-step explanation: here's why. probability is basically guessing by the way. so were trying to find the statement best describes the use of a simulation to predict the probability that two randomly chosen people will both have their birthdays on a Monday. all you have to do is make 1 and 7 a fraction like this: 1/7^2 thats why its d hope this helps

in a recent semester at a local university 520 students enrolled in both general chemistry and calculus 1. Of these students 88

Let Ch and C denote the events of a student receiving an A in chemistry or calculus, respectively. We're given that

P(Ch) = 88/520

P(C) = 76/520

P(Ch and C) = 31/520

and we want to find P(Ch or C).

Using the inclusion/exclusion principle, we have

P(Ch or C) = P(Ch) + P(C) - P(Ch and C)

P(Ch or C) = 88/520 + 76/520 - 31/520

P(Ch or C) = 133/520
