To do this, we first want to see how many participants there are in total by adding both males and females.
Now we know that there were 220 total participants, but only 121 were females.

Answer:
.
Step-by-step explanation:
We are given that,
1, 2, 3 represents someone using a coupon and 4, 5 represents someone not using a coupon.
Now, the results out of 15 trials of the experiment are given to be:
43454, 24511, 55555, 43453, 55315, 25215, 32235, 43311, 11154, 13342, 42514, 13223, 44215, 45313, 13324.
Since, we can see that, the only possibilities where 4 or more customers use coupons are:
32235, 43311, 13342, 13223 and 13324.
That is, out of 15 trials, there are total 5 trials in which 4 or more customers use coupons.
Thus, the probability of 4 or more customers using a coupon is =
.
Hence, the required probability is .
