Hi
Binomial Distribution: n=6, p=0.6
Using TI or similarly an inexpensive calculator like a Casio fx-115 ES plus
P(X ≤ 3) = binomcdf(n, p, largest x-value) 
 binomcdf(6, .6, 3) = .45568  0r .4557  Rounded to four decimal places.

Agree with my distinguished colleague, recommend Using stattrek.com to check  Results  until You are familiar with Using Your Calculator.  
**Important to know what type of calculator may be used in a test situation.
