What is the probability of getting even numbers when a die is rolled?(a) \(\frac {1}{2}\)(b) \(\frac {3}{2}\)(c) \(\frac {1}{4}\)(d) 1The question was posed to me in an online interview.My question is from Theoretical Approach to Probability in section Probability of Mathematics – Class 10

Answer»

Correct choice is (a) \(\frac {1}{2}\)

EXPLANATION: Total NUMBER of outcomes are {1, 2, 3, 4, 5, 6} = 6

Even numbers in total outcomes are {2, 4, 6} = 3

P(E) = \(\frac {Number \, of \, FAVORABLE \, outcomes}{Total \, number \, of \, outcomes}\)

= \(\frac {3}{6}\)

= \(\frac {1}{2}\)
