Answer:
P(A) = 20 %
Step-by-step explanation:
let S be the sample space of the experiment,
n(S) = 3 red marbles +2 blue marbles +6 green marbles
∴ n(S) = 11
let A be the event of getting both the marbles drawn as a green marbles
∴ n(A) = 2
∴ [tex]Probability(A)=\frac{n(A)}{n(S)} \\\\P(A) =\frac{2}{11} \\\\P(A) = 0.1818\\\\P(A) = 0.2[/tex]
P(A) = 0.2 × 100 = 20%
