Question

At the pediatrician's office, patients are able to draw a toy from the toy bin. The toy bin has 12 puzzles, 16boxes of crayons, and 2 bouncy balls. What is the probability of drawing...a box of crayons?a puzzle?anything but a bouncy ball?(write your answer as a fraction in lowest terms)

Answer 1

Total outcomes = 12 puzzles + 16 boxes of crayons + 2 bouncy balls = 30.

`\begin{gathered} \text{Probability = }\frac{required\text{ outcome}}{\text{total outcome}} \\ \\ \text{probability of drawing a box of crayons = }(16)/(30)=\text{ }(8)/(15) \end{gathered}`
`\text{Probability of drawing a puzzle = }(12)/(30)\text{ = }(2)/(5)`

Probability of anything but bouncy ball means the probability of drawing out a box of crayons or probability of drawing out a puzzle.

`\begin{gathered} \text{This becomes = }(8)/(15)+(2)/(5) \\ \\ =\text{ }(8+6)/(15)\text{ = }(14)/(15) \\ \end{gathered}`
