More than five lol sorry I am only trying to help
The answer is c because the a and b work together to combined a like for
X 1 2 3 4
p(x) 0.40 0.20 0.15 ?
If the items are only 4. The total of the probability must be 1 or 100%
1 - 0.40 - 0.20 - 0.15 = 0.25
The probability of 4 is 0.25.
N-10 because you want to take 10 away from n
