A letter is chosen at random from the word “ROSE”. Find the probability, that the letter chosen is a vowel. 

Correct Answer - (i) 0.57 (ii) 0.43

Correct Answer - (i) 0.71 (ii) 0.29

Correct Answer - `(191)/(200) `

Let X be the random variable defined as the number of red balls. Then X = 0, 1 P(X = 0) = \(\frac{3}{4}\times\frac{2}{3}=\frac{6}{12}=\frac{1}{2}\) P(X = 1) = \(\frac{1}{4}\times\frac{3}{3}+\frac{3}{4}\times\frac{1}{3}=\frac{6}{12}=\frac{1}{2}\) Probability Distribution Table: X 0 1 P(X) \(\frac{1}{2}\) \(\frac{1}{2}\)

The required probability = P((The first is a red jack card and The second is a jack card) or (The first is a red non-jack card and The second is...

Correct option is A) indivisible

Correct option is (A) 0 A month have at most 31 days in a calendar year. \(\therefore\) There are no month which have 32 days. \(\therefore\) Favourable outcomes = 0 Total month = 12 \(\therefore\) Probability that random...

Correct option is (C) \(\frac5{11}\) Total number of S's in "ASSESSMENTS" = 5, Total number of E's in "ASSESSMENTS" = 2, A, M, N & T are 1 time occur in word "ASSESSMENTS". \(\therefore\) Total letters in...

Total number of possible outcomes, n(S) = 50  Number of favorable outcomes,  n(E) = 4 ∴ P(E) = \(\frac{n(E)}{n(S)}\)= \(\frac{4}{50}\) = \(\frac{2}{25}\)
