Probability can be expressed as a ratio of desired cases to the whole number cases possible.
So, there a total of 60 pieces of taffy and we want to know what are the chances of drawing a raspberry taffy. We know there are 18 pieces of taffy that are raspberry flavor.
We can express this as a ratio. 18:60.
Simplify.
18:60 = 3:10
Convert the ratio into a decimal. To do this, divide the top by the bottom.
3:10 = 0.3
Now make it into a percent. Just move the decimal point two places to the right and make into a % sign.
0.3 = 30%
So, there will be a 30% of drawing a raspberry flavored taffy piece.
