Question

Disjointed and overlapping events

Answer 1

1. P = 0.269 or 26.9%

2. P = 0.372 or 37.2%

Step-by-step explanation:

First, let's calculate the total number of students:

So, we know that the number of students is 662.

Now, let's evaluate the probabilities:

1. Student will begin college during summer AND attend an in-state college.

P = 178/662

P = 0.269 or 26.9%

2. Student will begin college in summer GIVEN THAT he is attending an in-state college.

In this case, the total number of students will be the number of students who will attend an in-state college.

P = 178/479

P = 0.372 or 37.2%
