To calculate: The probability of drawing 2 red marbles from a bad that contains one green, two yellow and three red marbles without replacement.
Answer to Problem 31E
The probability to draw two red marbles is
Explanation of Solution
Given information:
An experiment that draws two marbles from a bag that contains one green, two yellow and three red marbles without replacement.
Formula used:
The probability of an event is the ratio of number of possible outcomes of an event E denoted by
Calculation:
Consider the provided experiment that draws two marbles from a bag that contains one green, two yellow and three red marbles without replacement.
Total number of marbles are 6.
Recall that the probability of an event is the ratio of number of possible outcomes of an event E denoted by
Denote the event
Since, the experiment is done without replacing the marbles and two marbles are drawn.
Denote the event
So,
Probability that both red marbles are drawn is,
Thus, the probability to draw two red marbles is
