What is probability?

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Given that:-

• A spinner is divided into 12 equal sectors labelled with the letters A through L
• The spinner is spun 80 times

• How many times is it expected that a vowel will be spun?

The probability of the vowel to be spun will be:

A B C D E F G H I J K L

Vowels are:-

A ,E ,I

=  12  x   3

=  36

Therefore the number of times is it expected that a vowel will be spun will be 36.
