1.	A letter is chosen at random from the word “ROSE”. Find the probability, that the letter chosen is a vowel. A) 1/4B) 3/4C) 1/2D) 2/5
Answer» Correct option is (C) 1/2 R & S are consonant and 0 & E are vowels in word ROSE. Total number of letters in ROSE is n(S) = 4 Total vowel letters in ROSE is n(V) = 2 \(\therefore\) P(V) \(=\frac{n(V)}{n(S)}=\frac24=\frac12\) Hence, the probability that the letter chosen is a vowel is \(\frac{1}{2}.\) Correct option is C) 1/2

A letter is chosen at random from the word “ROSE”. Find the probability, that the letter chosen is a vowel. A) 1/4B) 3/4C) 1/2D) 2/5

Answer»

Correct option is (C) 1/2

R & S are consonant and 0 & E are vowels in word ROSE.

Total number of letters in ROSE is n(S) = 4

Total vowel letters in ROSE is n(V) = 2

\(\therefore\) P(V) \(=\frac{n(V)}{n(S)}=\frac24=\frac12\)

Hence, the probability that the letter chosen is a vowel is \(\frac{1}{2}.\)

Correct option is C) 1/2
