A bag contains 2 green, 9 brown, 7 yellow, and 4 blue marbles.

Once a marble is selected, it is not replaced.

Find each probability.

3. P(yellow, then yellow)

Oa 1/11

Ob 2/13

1/6

3/14

Step-by-step explanation:

Given data

2 green,

9 brown,

7 yellow, and

4 blue marbles.

Sample space S = 2+9+7+4= 22

The probability of picking a ball without replacement

Probability of picking each ball

Pr(green) = 2/22= 1/11

Pr(brown ) = 9/21

Pr(yellow) = 7/20

Pr(blue) = 4/19

Probability of picking yellow then another yellow

P(yellow, then yellow)

=(7/22)*(6/21)= 42/462

=1/11

A. 1/11

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35
