Need help with a question

Q2:A box contains 3 gummy bears, 4 marbles, and 7 bottle caps. a child sticks his hand into the box and pulls out 5 items. What is the probability that he would NOT get any gummy bears?


for this question do you just do [(3C0)(11C5)]/(5C14) ?
 
No. Notation in numerator or denominator can't be right. You must pick what means what.
