Expert Solution
Step 1

From the given information,

The probability of success, p=72.5%=0.725.

Sample size=8

If X=0:

P(X=0)=0.00003, obtained from the excel function, =BINOM.DIST(0,8,0.725,FALSE).

 

If X=1:

P(X=1)=0.00069, obtained from the excel function, =BINOM.DIST(1,8,0.725,FALSE).

Similarly the probability values for X=2, 3, 4, 5, 6, 7, 8 are obtained below:
