Abook shelf holds twenty books. eleven are hard- covered, nine of the books are nonfiction, and four of the nonfiction books are hard-covered, as shown in the venn diagram. let event h be a hard-covered book and let event n be a nonfiction book

1) Find the probability that a chosen book is nonfiction and hard-covered. P(N ∩ H) = 4/20

2) Find the probability that a chosen book is hard-covered. P(H) =  11/20

3) Calculate the conditional probability. = 4/11

1.) 4/20

2.) 11/20

3.) 4/11

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
