The required probability buys a drink also buying chips is 0.66.
At a sandwich shop, 42% of customers buy a drink with their sandwich Only 28% of customers buy a drink and chips with their
sandwich. the probability that a customer who buys a drink also buys
chips is to be determined.
What is probability?
Probability can be defined as the ratio of favorable outcomes to the total number of events. The value of probability ranges from zero to one but cannot be negative. probability p (A) = number of favorable outcome / total sample space
Total number of samples = 42%
The total number of favorable outcomes is = 28%
Required probability for the people that a customer who buys a drink also buys chips = Favorable outcome / total sample
= 28/42
= 0.66
Thus, the required probability buys a drink also buying chips is 0.66.
