b) 5
c) 9
d) 12

Answer 1

To be certain of taking at least one flavor, Tom must take out 9 jelly babies from his pocket.

Step-by-step explanation:

Tom has 8 strawberry jelly babies, 4 lime jelly babies, and 4 cola jelly babies in his pocket. To be certain that he takes at least one flavor, he would have to take out all the strawberry jelly babies, all the lime jelly babies, and one cola jelly baby because after taking out 8 strawberry jelly babies and 4 lime jelly babies, there could still be no cola jelly babies left in his pocket.
