Given that, X is binomial random variable.
We want to find, the following probabilities using binomial probability table.
a) For n = 10 and p = 0.1
P(X = 4) = P(X ≤ 4) - P( X ≤ 3) = 0.998 - 0.987 = 0.011
P(X = 4) = 0.011
b) For n = 15 and p = 0.5
P(X ≤ 5) = 0.151
c) For n = 5 and p = 0.3
P(X > 1) = 1 - P(X ≤ 1) = 1 - 0.528 = 0.472
P(X > 1) = 0.472
d) For n = 15 and p = 0.7
P(X < 4) = P(X ≤ 3) = 0.000
e) For n = 25 and p = 0.9
P(X ≥ 18)
= 1 - P(X < 18)
= 1 - P(X ≤ 17)
= 1 - 0.002
= 0.998
P(X ≥ 18) = 0.998
f) For n = 20 and p = 0.2
P(X = 4) = P(X ≤ 4) - P(X ≤ 3) = 0.630 - 0.411 = 0.219
P(X = 4) = 0.219
