Suppose your friends have the following ice cream preferences:

  • 42% of your friends like chocolate (C). The remaining do not like chocolate.

  • 12% of your friends like sprinkles (S) topping. The remaining do not like sprinkles.

  • 9% of your friends like Chocolate (C) and also like sprinkles (S).

Of the friends who like sprinkles, what proportion of this group likes chocolate? (Note: Answers are rounded to four decimal places.)

Solutions

Expert Solution

P(C) = 0.42

P(S) = 0.12

P(C and S) = 0.09

P(C | S) = P(C and S) / P(S) = 0.09 / 0.12 = 0.75 (ans)
