The probability that a parent will visit a restaurant after kids game is know to be .68 and assumed the same for all parents. Assuming customer visits are independent and identical, determine the probability that 5 of 7 parents selected at random visit the restaurant. Calculator only. Need help understanding how to set this up.

Formula:
P(x) = (nCx)(p^x)[q^(nx)]
n = 7
x = 5
p = .68
q = 1  p = .32
Substitute into the formula and calculate.
