Question

What is the probability of picking a vowel (a,e,i,o,u) and rolling a 3 or less on a die?

Answer 1

Answer:

$\frac{5}{52}$

Step-by-step explanation:

In probability,

"AND" means "MULTIPLICATION"

"OR" means "ADDITION"

Here, we want Probability of "picking a vowel" and "rolling 3 or less".

So we have to find individual probability and MULTIPLY.

Probability of picking a vowel:

There are 26 letter in the alphabet out of which 5 are vowels, so

P(vowel) = 5/26

Probability of rolling 3 or less:

There are 6 numbers in a die (1-6) and rolling 3 or less is 3, 2, 1. So 3 numbers.

P(rolling 3 or less) = 3/6 = 1/2

Now we multiply:

$\frac{5}{26}*\frac{1}{2}=\frac{5}{52}$

This is the answer.
