Question

For Chapter 5, thoroughly describe how you would find the answer to the following question, and include an attachment of a detailed drawing of the tree diagram for this problem, labeled with outcomes and associated probabilities.

In a jar are 76 balls: 13 are red, 13 are white, and 50 are blue. You draw out two balls without putting any back in. What is the probability that the balls you've drawn are one red and one white, though not necessarily in that order?

Answer 1

Total number of balls = 76

Number of red balls = 13

Number of white balls = 13

Number of blue balls = 50

Probability of red ball = 13/76

Probability of white ball = 13/76

The probability that the balls drawn are one red and one white =(13/76) +(13/76) = 0.3421             (Round to 4 decimal)

The probability that the balls drawn are one red and one white = 0.3421
