Answer:
Probability is 0.65
Step-by-step explanation:
From the question, out of the first 20 people ben saw, he saw that 13 wore jackets while 7 did not.
Thus, if that is the case, it means that the experimental probability that the next person he will see will be wearing a jacket will be given as;
Number of people wearing jacket/total number of people ben saw = 13/20 = 0.64
