Question

Two dice are thrown simultaneously. Find the probability of getting :
i)an even number as the sum
ii)in the sum as a prime number
iii)a total at least 10
iv) a doublet of even number
v)a multiple of 2 on one dice and a multiple of 3 on the other
vi)Same number on both dice ie, a doublet
vii) a multiple of 3 as the sum.​

Answer 1

Answer:

Above shown is the outcome table when two dice are thrown

[1]sample space when. sum is even

(1,1),(2,2),(3,3),(4,4),(5,5),(6,6)

(1,3),(1,5),(3,1),(5,1),(4,2),(6,2)

(5,3),(2,4),(6,4),(3,5),(2,6),(4,6)

total possibilities=18

total no.of outcoems =36

therefore

probality that sum is even number=18/36

=1/2
