Hi
Binomial Distribution:  p(pass completion) = .62
Using TI or similarly an inexpensive calculator like a Casio fx-115 ES plus 
n = 16
(a) P(x = 12) = binompdf(16, .62, 12) = .1224
(b) P(x > 6) = 1 - P(x ≤  6)= 1 - binomcdf(16, .62, 6) = 1-.0411 = .9589
(c) Expected = .62 * 16 = 9.92  or 9 (rounded down to whole number)

Important You are  comfortable using Your Calculator.
Wish You the Best in your Studies.
