Question

a bag contains 8 red marbles, 3 blue marbles, and 1 green marble. find p(not blue). a. 9 b. \\(\frac{4}{3}\\) c. \\(\frac{1}{4}\\) d. \\(\frac{3}{4}\\) please select the best answer from the choices provided a b c d

Explanation:

Step1: Find total number of marbles

Total marbles = Red + Blue + Green = \(8 + 3 + 1 = 12\)

Step2: Find number of non - blue marbles

Non - blue marbles = Red + Green = \(8 + 1 = 9\)

Step3: Calculate probability of not blue

Probability \(P(\text{not blue})=\frac{\text{Number of non - blue marbles}}{\text{Total number of marbles}}=\frac{9}{12}=\frac{3}{4}\)

Answer:

D. \(\frac{3}{4}\)
