Question

The owner of a small deli is trying to decide whether to discontinue selling magazines. He suspects that only 9.6% of his customers buy a magazine and he thinks that he might be able to use the display space to sell something more profitable. Before making a final decision, he decides that for one day he will keep track of the number of customers that buy a magazine. Assuming his suspicion that 9.6% of his customers buy a magazine is correct, what is the probability that exactly 2 out of the first 10 customers buy a magazine

Answer 1

Answer:

The probability that exactly 2 out of the first 10 customers buy a magazine

=

1.92%

Step-by-step explanation:

The Proportion of customers who buy a magazine = 9.6%

If 2 out of the first 10 customers buy a magazine, the proportion is given as  2/10 or 20%.

Therefore, the probability that exactly 2 out of the first 10 customers will buy a magazine is equal to the proportion of customers who buy a magazine multiplied by the proportion of the first 10 customers who buy a magazine

= 9.6% * 20%

= 1.92%
