PLEASE HELP ME 60 POINTS

Answer 1

Answer: Hence,  the probability that, out of the next 5 customers, 4 or more will use a coupon is:

                 1/3

Step-by-step explanation: Total 15 trials were recorded as follows:

43454   24511   55555  43453     55315    25215    32235      43311      11154  13342   42514    13223      44215   45313  13324

Now, we are asked to find the probability that, out of the next 5 customers, 4 or more will use a coupon.

We know that probability is the ratio of number of favorable outcomes to the total number of outcomes.

 Hence, number of favorable outcomes are: 5

(32235    43311   13342    13223   13324  )

Total number of outcomes are: 15

( Since 15 trials were performed)

Hence, Probability is:  5/15 = 1/3

 Hence, the answer is: 1/3
