12 shade out of 15 boxes which gives 0.8 chance of picking a shaded one.
<h3>What is the probability?</h3>
Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
There are 15 sections given
To make the probability of choosing a shaded section randomly 0.8,
So,
0.8 of 15
0.8 is equal to 80%
we need to figure out 80% of the 15
80% of 15
80% × 15
= 12
Hence, we would need to shade 12 out of 15 boxes which gives 0.8 chance of picking a shaded one.
