Question

Two dice are thrown at the same time.find the probability of getting
A) both are same face
B) sum of two numbers appearing an two dice is greater than 9

Answer 1

Answer:

(A) 1/6

(B) 1/2

Step-by-step explanation:

n(s)=36

E1= both are same face (which means the number appeared should be same on both dices)

n(E1)=6

P(E1)=6/36

=1/6

E2= sum of two numbers appearing an two dice is greater than 9

n(E2)=18

P(E2)=18/36

=1/2

Answer 2

As there are two dice, the total no. of outcomes is 6^2 = 36.

(A) There are a total of 6 possibilities in which the numbers in both the dice are same: (1, 1), (2, 2), (3, 3), (4, 4), (5, 5), (6, 6).So the probability is 6/36 = 1/6

(B) The possibilities in which the sum of the numbers in the dice is greater than 9 are given: (4, 6), (5, 5), (5, 6), (6, 4), (6, 5), (6, 6). Thus the no. of favourable outcomes is 6. So the probability is also 6/36 = 1/6.
