Answer:
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
