Question

Two dice are thrown simultaneously. Find the probability of getting a sum of 10 or more if 5 appears on the first die​

Answer 1

Sample Space, S = [ (5,1), (5,2), (5,3), (5,4), (5,5), (5,6) ]

No. of favourable outcomes = 2

Hence, P(sum of 10 or more) = 2/6 = 1/3

Answer 2

Outcomes can be

5,1

5,2

5,3

5,4

5,5

or 5,6

Favourable outcomes = 2

Total number of outcomes = 6

Therefore,

The probability will be 2/6 = 1/3
