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

40 minutes

step-by-step explanation:

add the time and multiply by 2

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
