Hi  
Normal Distribution: µ = 55 and σ = 8  ≤
Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus
Since this is a continuous function, we have P(x < 65) = P(x ≤ 65).

P(x ≤ 65) = normalcdf(-9999, 65, 8, 55) = .8944   |NOte: -9999 a placeholder)

Important You feel comfortable using Your Calculator.
Key to Your success in working with the Various Distributions.
Wish You the Best in your Studies.
