Timed a survey asked about the number of people who eat breakfast almost every day (b) and the number of people who buy cereal at least once a month (c). the results of the survey are shown in the venn diagram. given that a randomly chosen person eats breakfast almost everyday, what is the probability that the person also buys cereal at least once a month?

Given a venn diagram in picture representing two sets.  The blue set B represents the number of people who eat break fast almost every day. the orange set C represents the number of people who buy cereal atleast once a month.

n(B) = 11+53 =64

n(c) = 53+4 = 57

n(BC) = 53

Required probability = (Prob that the person buys cereal atleast once a month/he eats breakfast almost every day)

= P(C/B) = P(BC)/P(B) = n(BC)/n(B) = 53/64

Hence answer is 53/64

Option 3 is the right answer.

ian gonna lie that is way to much
