Chapter 8.4, Problem 48HP

To determine

The probability of the balloon.

Answer to Problem 48HP

  $\frac{8}{13}$ .

Explanation of Solution

Given information:

A vendor has $14$ helium balloons for sale: $9$ are yellow, $3$ are red, and $2$ are green. A balloon is selected at random and sold. If the balloon sold is yellow, what is the probability that the next balloon, selected at random, is also yellow?

Calculation:

Total number of balloons $=14$

  $1$ Of the yellow balloon was sold out of nine $=$ $8$

One less out of the total balloon $=13$

So that,

  $\frac{8}{13}$

Thus, the solution is $\frac{8}{13}$.
