Sample space={5 B + 6 R + 9 G} = 20 (all possible outcomes
Favorable outcome ={6 R} = 6
P(1st Drawing R) = 6/20 = 3/10
Once drawn and not replaced the total remaining marble = 19 and within the 19, there are 5 Red left. So
P(2nd Drawing R) = 5/19
P( 1st AND 2nd R) = (3/10)x(5/19) = 3/38 = 0.0789
Answer: she would get 100%
Step-by-step explanation: every correct question u get 5 points so 20 * 5 = 100
A, B and D are true

9 / 15
9 / 3 = 3
15 / 3 = 5
so 3 / 5
60/100
6/10
The probability that the ball Deborah picks is green is; 3/5.
<h3>What is the probability that the ball picked last is green?</h3>
Since the bag initially contains; 3 red balls, 4 green balls, and 2 yellow balls, after Deborah pulls out the 4 balls: red, red, green, yellow.
The balls remaining are; 1 red ball, 3 green and 1 yellow.
Hence, the probability that the final ball she picks is green is; 3/(3+1+1) = 3/5.
