Answers:
A. 2/15, 0.40, 0.47

B. 0.40, 7/15, 2/15

C. 0.4, 0.13, 0.47

D. 2/15, 7/15, 0.40

Answer 1

Answer:

A. 2/15, 0.40, 0.47

Step-by-step explanation:

6 green tennis balls

2 yellow tennis balls

7 red tennis balls

15 total tenis balls

probability that the first tennis is a yellow ball:

$\frac{2}{15}$

probability that the second tennis ball is green:

$\frac{6}{15} = 0.40$

probability that the third tennis ball is red:

$\frac{7}{15} = 0.4666 = 0.47$

Answer 2

I think it’s D because you count the total tennis balls together which gives u a denominator of 15. So it’s 2/15 and 7/15 and 6/15. Since 6/15 is not on option D. I made 6/15 into a decimal which was 0.4 and 0.4 is the same as 0.40. So the answer is D.
