Question

Martin has 6 yellow balloons, 9 red balloons, and 5 green balloons for sale. A balloon is selected at random and sold. What is the probability that the balloon selected at random is yellow?1/49/203/203/10

Answer 1

We need to divide the event of interest, 6 possible yellow baloons, by the total number of events.

$\begin{gathered} p=\frac{6}{6+9+5} \\ p=\frac{6}{20} \\ p=\frac{3}{10} \end{gathered}$

The probability of selecting one possible ballon is 3/10.
