Brainliest answer on a timer a bag contains three yellow tennis and four green tennis balls. gordy will select one tennis balls, put it in his pocket, and then select a second tennis ball. which expression gives the probability that he will select two green tennis balls a. 4/7 • 3/6 b. 4/7 • 4/6 c. 4/7 • 3/7 d. 4/7 • 4/7

The answer is C i.e the probability is

Step-by-step explanation:

Given 3 yellow tennis and 4 green tennis balls.

Now, Gordy will select one tennis balls which is green then the probablility of drawing one green tennis ball is

P(green tennis ball) =

Now another ball is chosen randomly without replacing that first ball which is also green therefore the events are dependent. Hence, conditional probability

P(green on second pick given green on first pick) =  

Hence, Probability of both green tennis balls will be

P(two green tennis balls) =

                                          =

7200

aye bru this a great thing your doin here.

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
