Question 1178349

Hi
Binomial Distribution:  p(cheese) = ".35"   and q = .65
Using TI or similarly an inexpensive calculator like a Casio fx-115 ES plus
a) n = "3" 
P(x = 3) = binompdf(3, .35, 3) = .0429
b) n = "4"
P(x = 3) = binompdf(4,.35,3) = .1115
0r
{{{P (x)= highlight_green(nCx)(p^x)(q)^(n-x) }}} 
a) {{{P (x=3)= highlight_green(3C3)(p^3)(q)^0 }}} = (.35)^3 = .0429
b) {{{P (x=3)= highlight_green(4C3)(p^3)(q)^1 }}} = 4(.35)^3(.65)^1 = .1115
Wish You the Best in your Studies.
