Abag contains 3 red, 4 blue, 3 green, and 5 yellow marbles. what is the probability of
picking two green marbles in a row, without replacing the first marble?

1/35 ≈2,85%

Step-by-step explanation:

Total possible outcomes for the first pick: 3+4+3+5 = 15

Probability of picking a green marble for the first pick : 3/15 = 1/5

Total possible outcomes for the second pick: 15-1(the first pick) = 14

Probability of picking a green marble for the second pick : 3-1(first pick)/14 = 2/14 = 1/7

Probability of picking green marble 2 times in a row = 1/5 * 1/7 = 1/35 ≈2,85%

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
