Suppose there are 100 students in your accounting class, 10 of whom are left-handed. two students are selected at random. 1. draw a probability tree and insert the probabilities for each branch.

Given that among the 100 students, 10 are left-handed, the probability of picking a left-handed out of the class is approximately equal to 10/100 or 10%. If two are selected at random, the possibilities are that: (1) two are left-handed, (1) one is left-handed and the other is not, (3) none of them is left-handed.
