To solve this question, use the Binomial probability formula.
The formula is given by
Where:
n = the number of trials
x = the sample we aim to try
p = the probability of success
In this question:
n = 16
x = 9
p = 0.5
Substituting in the equation:
And the combination formula:
Then:
Answer: The probability is 0.1746.
