Julie is taking two books with her on vacation. suppose the probability she likes the first book is 0.5, the probability she likes the second book is 0.4, and the probability she likes both books is 0.3.
a. what is the probability she likes at least one of the books?
b. what is the probability she likes neither of the books?

Using Venn probabilities, it is found that there is a:

a) 0.6 = 60% probability she likes at least one of the books.

b) 0.4 = 40% probability she likes neither of the books.

This question is solved using Venn probabilities, and we are going to say that:

The probabilities given are: .

Item a:

This probability is:

Then

0.6 = 60% probability she likes at least one of the books.

Item b:

This probability is:

.

0.4 = 40% probability she likes neither of the books.

A similar problem is given at link

a. 0.6

b. 0.4

Step-by-step explanation:

Let's call

B1: she likes the first book

B2: she likes the second book

Then, P(B1) = 0.5, P(B2) = 0.4 and P(B1∩B2) = 0.3

a. she likes at least one of the books = P(B1∪B2) = P(B1) + P(B2) - P(B1∩B2)  = 0.6

b. she likes neither of the books = she doesn't like at least one of the books = 1 - P(B1∪B2) = 0.4

aloha~! my name is zalgo and i am here to you out on this gracious day. in order to compare the ratios easily, it is best that we simplify the question first. so, the cougars would have 6 wins for 5 losses, bobcats make 2 wins for 1 loss. bulldogs and tigers have a ratio where you can't simplify it. so, the team with the lowest rate would be the bobcats.

i hope that this ! : d
