Probability of choosing

Question

At a candy shop, Mendy decides to buy 8 mints and 4 chocolates now if she was not paying attention what is the probability of her not choosing a mint?

Answer 1

If Mendy randomly chooses (not paying attention) what is the Probability that she does NOT choose a mint.

So we're trying to find P (not mint).

P (not mint) = # of not mint items

total # of items

P (not mint) = 4

12

P (not mint) = 1/3 or 33.333%

Check it!

To make sure that makes sense, we can find the Probability she DOES find a mint,

which would be = # of mints 8 = 2 = 66.67%

total # of items 12 3

Since there only mints and NOT mints in the bag, the sum of these probabilities MUST equal 1. Do they?

Great job!
