Question 922358
Re TY
to Find: P(x ≤ 30)= .9555
TI: 2nd, VARS, binomcdf(need to scroll down to find) and enter (60, .40, 30)
Excel: function: BINOM.DIST(30,60,0.4,TRUE) 
........
p(minority) = .40,  n = 60
P(x > 30) = 1 - P(x ≤ 30) =   1 - binomcdf(60, .40,30)  TI Calculator
P(x > 30) = 1 - .9555 = .0445  0r 4.45%

One could also Use Your Casio fx-115 ES plus 0r fx-991 ES plus 
In a similar fashion: Mode: DIST(binomial CD).
