Question

A bag contains 5 red tokens, 3 blue tokens, and 2 yellow tokens. If you draw a token at random and then put it back in the bag, the probability that you will draw the same token again is 10%.





A.
True



B.
False

Answer 1

well it all depends on which token you pulled out

Answer 2

Let's look at the probability of choosing a red token twice in a row. Each time you have a probability of 1/2 of choosing a red token. Thus, the probability of choosing it twice in a row is \[{1 \over 2}\cdot{1 \over2}={1\over4}=0.25=25\%\]This is greater than 10%, so the answer would be false.

Answer 3

but yellow is 10%??? so true and blue is 15% soooo huh???
