Question

The results of an awesome survey question are shown below.

If there were a popsicle stick for each selection, what is the probability of selecting one that says books without pictures, replacing it, and then selecting one that says audio books?
Round your answer to the nearest hundredth.

Answer 1

Explanation:

total number of sticks = 47+36+31= 114

Because you draw with replacement to find the probability of two events happening you simply just multiply them

p(books without pics) = #books without pics /#sticks

47/114 = 41.2280702%

p(audiobooks)= #audiobooks/ #sticks

31/114= 27.1929825%

p(books without pics and audiobooks)= p(books without pics) * p(audiobooks)

41.2280702%*27.1929825% = 11.21%
