When a dice is rolled the probability of getting a composite number i

1.	When a dice is rolled the probability of getting a composite number isA) 1/3B) 1/4C) 1/2D) 1/6
Answer» Correct option is: A) \(\frac{1}{3}\) When a dice is rolled, then possible outcomes are {1, 2, 3, 4, 5, 6} Total No of outcomes is n (S) = 6 Composite numbers from 1 to 6 are {4, 6} Total No of composite numbers from 1 to 6 is 2 \(\therefore\) Probability of getting a composite number = \(\frac {Total \,No\, of \,composite \,number}{Total \, No \, of\, Possible \, outcomes}\) = \(\frac 26 = \frac 13\) Correct option is: A) \(\frac{1}{3}\)

When a dice is rolled the probability of getting a composite number isA) 1/3B) 1/4C) 1/2D) 1/6

Answer»

Correct option is: A) \(\frac{1}{3}\)

When a dice is rolled, then possible outcomes are

{1, 2, 3, 4, 5, 6}

Total No of outcomes is n (S) = 6

Composite numbers from 1 to 6 are {4, 6}

Total No of composite numbers from 1 to 6 is 2

\(\therefore\) Probability of getting a composite number

= \(\frac {Total \,No\, of \,composite \,number}{Total \, No \, of\, Possible \, outcomes}\)

= \(\frac 26 = \frac 13\)

Correct option is: A) \(\frac{1}{3}\)
