Hi
Binomial Distribution:   p = .45  q = .55   n = 260
Using Calculator(either TI or similarly inexpensive Casio fx-115 ES plus 
a) P( x ≥ 100)= 1 - P(x ≤ 99) = 1 -.0142 = .9858

b) P( x < 125) = P(x ≤ 124) = .8252

c) P( 91 < x < 112) = P(x ≤ 111) - P( x ≤ 91) = .2469 - .0007 = .2462

Important You feel comfortable using Your Calculator
and know what one may use for in-class testing.
Wish You the Best in your Studies.
