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.
