Question

10. A glass jar contains 8 red, 6 green, 12 blue, and 10 yellow marbles. If a single marble is chosen at random from the jar, what is the probability of choosing a(a) red marble? (b) green marble? (c) blue marble?

Answer 1

Let:

• A ,be the event of getting a red marble

,

• B ,be the event of getting a green marble

,

• C ,be the event of getting a blue marble

We'll have that:

`\begin{gathered} P(A)=(8)/(36) \\ \\ P(B)=(6)/(36) \\ \\ P(C)=(12)/(36) \end{gathered}`
