Question

You have 11 cards with the letters PROBABILITY with one letter per card. What is the probability of selecting a vowel (Let Y be a vowel)? Write your answer as a decimal rounded to two decimal places.


1) 0.55

2) 0.45

3) 1.00

4) 0.33

Answer 1

In the word PROBABILITY, there are 5 vowels (including the Y), which are O, A, I, I, and Y

We are given that one letter was written on each card, so there are 11 cards.

 

So, the chance of drawing one vowel will be 5/11 = 0.45

 

The answer is option 2
