That means that the probability of any one student drawn at random being male was .6. If you do that 4 times in a row and want all to be male the joing probability is .6x.6x.6x.6=0.1296.
That is about 1/8 odds of it being all males on 4 draws.

Assuming that the class size is large enough not to introduce errors, the answer is 0.6 ^ 4 = 0.6 x 0.6 x 0.6 x 0.6 =
6 x 6 x 6 x 6 / 10 x 10 x 10 x 10 = 1296 / 10000

0,6 times 0,6 times 0,6 times 0,6 if I remember correctly
60% being 0,6 of !00% being 1

i guess (0.6*0.6*0.6*0.6)=(36*36)/10000
