If you randomly select a letter from the phrase "Mario kart on the Wii's fun", what is the probability that it was like a vowel? (Your answer must be in the form of a reduced fraction.)

The probability that it is a vowel is 3/7

Step-by-step explanation:

For this we have to count the number of letters the phrase contains

"Mario kart on the Wii's fun" = 21

the phrase has a length of 21 letters

now we count how many vowels the phrase has

"Mario kart on the Wii's fun"

"aio a o e ii u" = 9

the phrase has 9 vowels

To know the probability we have to do the number of vowels over the number of letters

9/21

as it asks us that the fraction is reduced we have to simplify by 3

9 = 3*3 21 = 3*7

9/21 = 3*3 / 3*7

9/21 = 3/7
