प्रश्न

A dice is thrown once. Find the probability of getting a number between 3 and 8.

योग

उत्तर

Sample space = {1, 2, 3, 4, 5, 6} 

n(S) = 6 

E = the possible even numbers between 3 and 8 = {4, 5, 6} 

n(E) = 3 

Probability of getting an even number between 3 and 8 = P(S)

= `("n"("E"))/("n"("S"))`

= `3/6`

= `1/2`
