A drawer holds 8 red socks, 13 blue socks, and 15 green socks. what is the probability that a red sock will be drawn first and then a green sock (without replacement?

This is the concept of probability, given that there are 8 red socks, 13 blues socks and 15 green socks, we are required to find that the first socks chosen will a red then a green; Here we shall proceed as follows;

The events are dependent

P (choosing a red socks) = 8/36=2/9

P (choosing green socks after red) = 15/35=3/7

Thus the probability of choosing red socks then a green socks without replacement will be:

2/9*3/7

=2/21
