Question

two dice are thrown at the same time .find the probability of getting different numbers on both dice?

Answer 1

Total no. of outcomes=36
No. of favourable outcomes(when we get different nos. on both dice)=36-6=30

∴Probability of getting different numbers on both dice=30/36
                                                                                    =5/6 (Ans)
                                                                                 

Answer 2

Answer:

2 dice can be thrown in 6*6=36

let E =getting a same number on both sides

E={(1,1),(2,2),(3,3),(4,4),(5,5),(6,6)}

therefore....P(E)=n(E)/n(S)

. =6/36=1/6

probability of getting different number on both the dice

=1-prob. of getting same number on both the dice

=1-1/6=5/6

hope this helps u
