A bucket contains 6 green tennis balls, 2 yellow tennis balls, and 7 red tennis balls. Tony removes 3 tennis balls, with replacement, from the bucket.

What is the probability that the first tennis ball is yellow, the second tennis ball is green, and the third tennis ball is red?

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

Answers

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:

[tex]\frac{2}{15}[/tex]

probability that the second tennis ball is green:

[tex]\frac{6}{15} = 0.40[/tex]

probability that the third tennis ball is red:

[tex]\frac{7}{15} = 0.4666 = 0.47[/tex]

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.

Mike has 40 baseball cards. Tim has 5 less than half of what Mike has. How many baseball cards does Time have?

Answers

Answer:

Give Branliest PLz

Answer is 15

Step-by-step explanation:

Half of 40 is 20 cause 40/2=20

Five less than 20 is 20-5 which= 15

So ur answer is 15

Answer:

Step-by-step explanation:

1. We know that Mike has 40 baseball cards total. We know that Tim has 5 less than half of the cards that Mike has.

2. First, we need to divide 40 (Mike's total amount of baseball cards) by 2 or multiply that by 1/2. That gives us 20 baseball cards.

3. Tim has 5 less than half of Mike's deck (20 baseball cards) so we have to take away 5 more cards. 20 - 5 = 15. Tim has 15 baseball cards.
