- Suppose there are 100 students in your accounting class, 10 of whom are left-handed.

- Two students are drawn at random. Draw the probability tree and insert the probability for each branch.

What is the probability of the following events?

- Both are right-handed?
- Both are left-handed?
- One is right-handed and the other is left-handed?
- At least one is right-handed?

Step 1

1)The letter R represents right-handed student and L represents left-handed student. The probability tree and corresponding probabilities is given below:

Step 2

Probability of given events:

1)The probability that both student selected are right-handed is calculated as follows:

Step 3

2)The probability that both student selected ar...
