I think 29 because Samantha is 5 year older than Luis
Answer:
The most likely outcome is exactly 4 free throws
Step-by-step explanation:
Given
--- attempts
---- probability of a successful free throw

Required
A histogram to show the most likely outcome
From the question, we understand that the distribution is binomial.
This is represented as:

For x = 0 to 5, where x represents the number of free throws; we have:


















From the above computations, we have:





See attachment for histogram
<em>From the histogram, we can see that the most likely outcome is at: x = 4</em>
<em>Because it has the longest vertical bar (0.4050 or 40.5%)</em>
P(TTTTT)=P(T)*P(T)*(PT)*P(T)*P(T)
P(TTTTT)=(P(T))^5
P(T)=1/2 so
P(TTTTT)=(1/2)^5
P(TTTTT)=1/32
P(TTTTT)=3.125%
