प्रश्न
In a single throw of a dice, find the probability of getting a number greater than 4.
उत्तर
Sample space = {1, 2, 3, 4, 5, 6}
n(s) = 6
E = event of getting a number greater than 4 = {5, 6}
n(E) = 2
Probability of a number greater than 4 = `(n(E))/(n(s)) = 2/6 = 1/3`

Two coins are tossed simultaneously. Complete the following activity to write the sample space and the given events A and B in the set form:
Event A: To get at least one head.
Event B: To get no head.
Activity:
Two coins are tossed simultaneously.
∴ Sample space is
S = `{square, HT, TH, square}`
Event A: To get at least one head.
∴ A = `{square, HT, TH}`
Event B: To get no head.
∴ B = `{square}`
