52. A basket contains 10 solid-colored balls—2 blue, 3 red, and 5 green. Each ball has a single number printed on it. The blue balls are numbered 1 and 2 (each number is used once), the red balls are numbered 1-3 (each number is used once), and the green balls are numbered 1-5 (each number is used once). A ball will be drawn at random from the basket. What is the probability that the ball that is drawn will be red or have a 3 printed on it?

Answer and Explanation

Your Answer is

Correct Answer is J

Explanation

The probability of drawing a red ball is 0.3, and the probability of drawing a number 3 ball is 0.2. Because there is a ball that is both a red ball and a number 3 ball. So the probability of drawing a red ball or a ball number 3 is 0.3+0.2-0.1 = 0.4
