From the letters of the word 'POSTER' a letter is selected. What is the probability that the selected letter is a vowel? |
$\frac{1}{6}$ $\frac{1}{3}$ $\frac{2}{3}$ $\frac{1}{2}$ |
$\frac{1}{3}$ |
If we see , 'POSTER' contains 2 vowels and total number of letters = 6 So the probability of the letter that is selected is a vowel = $\frac{2}{3}$ = $\frac{1}{3}$ |
