Question

a dice is rolled ,calculate the probability of getting a odd number on the top

Answer 1

Even number on dice : 2 4 6
Odd number on dice : 1 3 5
Total possible numbers :6
Probability : 3/6 = 1/2

Answer 2

The answer is given below :

When a dice is rolled, we get six results as
S = {1, 2, 3, 4, 5, 6}

So, n(S) = 6

The odd numbers are
P = {1, 3, 5}

So, n(P) = 3

Therefore, the possibility of getting a odd number on top

= n(P)/n(S)

= 3/6

= 1/2
