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

Activity : If two coins are tossed simultaneously
∴ s = {`square , "HT","TH", square`}
1) Event A : at least getting one head.
∴ A = {`"HH" , square , "TH"`}
2) Event B : to get no head.
∴ B = {`square`}
