Question

(19 POINTS QUESTION, HELP PLEASE) A bag contains 5 blue balls, 4 red balls, and 3 orange balls. If a ball is picked from the bag at random, what is the probability that it is a blue ball? Answers have been rounded to the tenths place. A. 0.5 B. 0.4 C. 0.3 D. 0.2

Answer 1

Answer:

B.  0.4

Step-by-step explanation:

5 + 4 + 3 = 12 balls

5 blue / 12 balls = 0.4

Answer 2

Answer: B

Step-by-step explanation:

1.) Calculate the percentage that blue balls make of the bag. First, add the balls together.

5 + 4 + 3 = 12

2.) Divide 100 / 12.

100 / 12 ≈ 8.3

3.) Multiply 8.3 by the number of blue balls.

8.3 * 5 ≈ 40

4.) Convert the percentage to decimal form.

40 / 100 = 0.4
