Two students are selected at random from a class of 8 boys and 9 girls. what is the probability that the 2 students selected are not girls? Answer by checkley79(3341) (Show Source):
You can put this solution on YOUR website! PROBABILITY THAT THE FIRST ONE SELECTED IS A BOY:
8/(8+9)=8/17=.47
PROBABILITY THAT THE SECOND ONE SELECTED IS A BOY
7/(7+9)=7/16=.44
.47*.44=.20 OR 20% PROBABILITY.
