Anyone out there who know how to solve these two problems :
If two dice are rolled, what is the probability of rolling a total of 4?
There are 4 black balls and 7 white balls in a drawer. If two balls are drwan at random ( one after the other without replacement) what is the probability of selecting two black balls?
Thanks guys
