In a single throw of a die, find the probability of getting a number
(i) greater than 2
(ii) less than or equal to 2
(iii) not greater than 2.
उत्तर
A die has six numbers = 1, 2, 3, 4, 5, 6
∴ Number of possible outcomes = 6
∴ P(E) = `4/6 = 2/3`
(ii)
Less than or equal to 2
Number of favourable outcomes = 1,2
∴ P(E) = `2/6 = 1/3`
(iii)
Not greater than 2
Number of favourable outcomes = 1,2
∴ P(E) = `2/6 = 1/3`
