Question

Ellie has two boxes of candy bars. The first box has 6 snickers, 5 kit kits, and 4 butterfingers. The second box has 3 snickers, 2 kit kats, and 4 butterfingers. If Ellie randomly selects one candy bar from each box, what is the probability that she will select a kit Kay from the bag?

Answer 1

Hi Kim,

Remember that probability is what you want/the total of what you have... so for the first box, you have 5 kit kats/15 total candy bars, or the probability is 5/15 or 1/3.

For the second box, do the same thing to find the probability of drawing a kit kat.

If she is taking one from each box, multiply 1/3 by what you got for box 2.
