Probability =
(number of ways it can come out the way you want)
divided by
(total number of ways it can come out).
Total number of ways to draw a marble = 30 (marbles in the bag).
Number of ways it can succeed = 15 (number of red or green ones)
Probability = 15/30 = 1/2 = 50% .
The probability is 4 out of 14
I think it's 8 b/c 24 minutes divided by 3 miles is 8 minutes per mile.
