Question

when two dice are thrown what is the probability of getting : (i) prime number on both. (ii)
a sum of 10.​

Answer 1

Answer:

Total outcome = 36

P(getting a prime number) = 6/36 = 1/6

Favourable outcomes for the above are - (2,3), (3,2), (2,5), (3,5), (5,2), (5,3)

P(getting sum of 10) = 3/36 = 1/12

Favourable otcomes for the above are - (4,6), (6,4), (5,5)

HOPE THAT THIS WAS HELPFUL!!!!

Answer 2

Step-by-step explanation:

total number of results that you can get = 36

total number of prime numbers = 9

p(of getting a prime number) = 9/36

= 1/4

p(of getting a sum of 10) = 3/36

= 1/12

total number of observation you can get in two dice

= 1,1 1,2 1,3 1,4..........1,6

2,1 2,2 2,3 ............... 2,6

3,1 3,2..................3,6

4,1...............4,6

5,1...............5,6

6,1 ............ 6,6
