Solve the following problems by using the binomial formula.
a. If n = 4 and p = .10 , find P(x = 3) .
b. If n = 7 and p = .80 , find P(x = 4) .
c. If n = 10 and p = .60 , find P(x ¡Ý 7) .
d. If n = 12 and p = .45 , find P(5 ¡Ü x ¡Ü 7) .

If you need to use the formula and work your problems instead of using the binomial probability table, here is the formula to use:
P(x) = nCx(p^x)[q^(n-x)]
For a:
x = 3
n = 4
p = .10
q = 1 - p = .90
I'll let you take it from here for the rest of your problems.

n = 4
