Answer:
The probability is 0.1312
Step-by-step explanation:
Here, let us set up a binomial system
From the question, 54% ride a bike
Let p = people that rides a bike
54% = 54/100 = 0.54
p = 0.54
q = 1 - p = 1 -0.54 = 0.46 ( 46% do not ride bikes)
Now, for the binomial system, we have
P(X = 15) = 30 C 15 • p^15•q^15
We have;
30 C 15 * 0.54^15 * 0.46^15
= 0.131200268998
The probability is 0.1312
