Question

David's gasoline station offers 4 cents off per gallon if the customer pays in cash. Past evidence indicates that 40% of all customers pay in cash. During a one-hour period, 15 customers buy gasoline at this station. This situation is an example of what type of discrete probability distribution

Answer 1

Answer: binomial probability distribution

Explanation:

given data:

n = 15

p = 0.4

10<=x<=15

From the given information Above,

we know customers are independent and probability of success is constant. Hence, our X obeys binomial distribution with given data’s n=15 and p=0.40.
