Ответ:
The probability is 0.29
Step-by-step explanation:
Firstly, we need to know the total number of retakes
That is simply the sum of the frequencies
we have this as;
27 + 29 + 18 + 14 + 12 = 100
so the probability of retaking exactly once will be the number of 1 retakes divided by total
That would be 29/100 = 0.29
