There are 5 black socks and 3 white socks in a drawer. tom randomly chooses one sock, does not replace it, and then chooses another sock. the tree diagram that represents the situation is shown below.

which fractions would be used to find the probability of getting white socks both times.

a)3/8 x 2/7=6/56= 3/28
b)3/8 x 5/7=15/56
c)5/8 x 3/7=15/56
d)5/8 x 4/7 =20/56=5/14
