Question

A bag contains ten tlles labeled B, C, D, E, F, G, H, I, J, and K. One tile will be randomly picked.What is the probability of picking a letter that is not a vowel?Write your answer as a fraction in simplest form.

Answer 1

The number of vowels is:

`2`

The total number of tiles is:

`10`

Therefore, the total number of letters not vowels is given by:

`10-2=8`

Hence, the probability of picking a letter that is not a vowel:

`(8)/(10)=(4)/(5)`

Therefore the required probability is 4/5
