Question

A bowl contains candles of the same size in three flavors :ORANGE,STRAWBERRY, AND PINEAPPLE.If the probability of randomly pulling out an orange candy is 4 over 7 ,and the probability of randomly pulling out a stawberry candy is 1 over 7 what is the probability of randomly pulling out a pineapple candy?

Answer 1

Hi!

To solve this, we need to write an equation.

Obviously there are 7 candies in the bowl.

$\frac{4}{7} + \frac{1}{7} + \frac{x}{7} = \frac{7}{7}$

Add

$\frac{5}{7} + \frac{x}{7} = \frac{7}{7}$

Subtract 5/7 from both sides of the equation to find x.

$\frac{5}{7} - \frac{5}{7} + \frac{x}{7} = \frac{7}{7} - \frac{5}{7}$

$\frac{x}{7} = \frac{2}{7}$

x = 2

The answer is $\frac{2}{7}$

Hope this helps! :)
