प्रश्न
A dice is thrown once. Find the probability of getting an even number or a multiple of 3.
उत्तर
Sample space = {1, 2, 3, 4, 5, 6}
n(S) = 6
E = the event of getting an even number or a multiple of 3 = {2, 3, 4, 6}
n(E) = 4
Probability of getting an even number or a multiple of 3 = P(S)
= `(n(E))/(n(S))`
= `4/6`
= `2/3`

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`}
