Mr. Yutaro’s class contains 10 boys and 6 girls. If two students are chosen, one at a time, from the class, what is the probability that a boy and a girl are chosen?  Choose the most appropriate option:
A) 9/48
B) 9/20
C) 11/24
D) 27/48
E) 1/2
Probability of a girl being chosen first, then a girl:   6/16 * 10/15   Probability of a boy being chosen first, then a boy:   10/16 * 6/15   Probability of a boy and a girl being chosen:   (6*10+6*10) / (15*16)   =1/2   Answer:1/2
