The probability that the 4th marble is black is:
P ( Black ) = 8 / 15 = 0.5333
After the 4th pick we have: 4 white, 3 red and 7 black marbles.
P ( Red or Black ) = 10 / 14 = 5 / 7 = 0.7143

The group of seventh graders will have 5 groups of five: 5 is the greatest multiple of 25, or 5*5=25.

Hope this helps.
