a, b, and c are independent, because they don't necessarily affect the probability of each other.
There are 5+6+4+3+2=20 m&m's in the bag.
Calculate in how many ways you can choose 3 m&m's from 20:

There are 6 yellow m&m's.
Calculate in how many ways you can choose 3 m&m's from 6:

The probability is 1/57.
Let's find his wpm (words per minute rate).
153 words / 3 minutes
/3 /3
51 words / 1 minute
51 words * 10 minutes = 510
He can type 510 words in 10 minutes
8:23, after 45 minutes is technically 8: 68
however, the hour ends at 60 minutes, so your true answer is 9:08 pm
hope this helps
