प्रश्न
A dice is thrown once. What is the probability of getting a number less than or equal to 2?
उत्तर
Number of possible outcomes when dice is thrown = {1, 2, 3, 4, 5, 6}
n(S) = 6
Event of getting a number less than or equal to 2 = E = {1, 2}
n(E) = 2
Probability of getting a number less than or equal to 2 = `(n(E))/(n(S)) = 2/6 = 1/3 `
