Question

21. Two dice are thrown at the same time, find the probability of getting,
a) same number on both dice.
b) sum of two numbers appearing on both the dice is eight.​

Answer 1

Step-by-step explanation:

(b) sum of two numbers appearing on both the dice is eight.

Answer 2

Answer:

There are a total of 36 outcomes,

$probability \: of \: an \: event = \frac{no \: of \: favourable \: outcomes}{total \: no \: of \: outcomes}$

a) getting same number= 6/36=1/6

the no of favourable outcomes=6 ((1,1)(2,2)(3,3)(4,4)(5,5)(6,6))

b) P(Sum of two numbers appearing eight)=4/36=1/9
