Question

A bag contains 5 black marbles and 4 white marbles. A spinner has 3 equal sections labeled 1 through 3.

What is the probability of drawing a black marble from the bag and spinning a 1 on the spinner?

A.5/9

B.1/2

C.2/9

D.5/27

Answer 1

\[ P(\text{black})=\frac{5}{9}\]\[P(\text{1 on spinner})=\frac{1}{3} \]
\[P(\text{black AND 1 on spinner})=P(\text{black})\cdot P(\text{1 on spinner}) \]
