FAN AND MEDAL
The number of marbles of different colors stored in a hat is listed below:
8 red marbles
10 green marbles
6 blue marbles
Without looking in the hat, Tessa takes out a marble at random. She replaces the marble and then takes out another marble from the hat. What is the probability that Tessa takes out a blue marble in both draws?

prob of blue marble =8/(8+10+6)
Now there is a replacement involved so we will have 8/24 * 8/24

sorry it should be 6/24
there are 24 marbles altogether
she has 6 in 24 chances of drawing blue on the first time (write that as a simper fraction)
the second time is INDEPENDENT of the first - so the chances are the same both times (she replaces the original blue one)
so the chances of 2 independent 6 in 24 events is???
it is not c
first simplify 6/24
and its c
I have to be persistent her:
you are not helping by giving wrong answers
it is not c
no - there are 2 draws
probability of 1 draw = 1/4
you multiply probabilities for 2 draws
