Question

two dice are thrown. Find the probability of getting.

(a) Same number on both the dice (b) Sum of the numbers appeared 11 (c) Sum 13​

Answer 1

Answer:

n (S) =12

a) let A be the probability of getting same no. on both sides

n (A)=6

=) P (A)=n (A)/n (S)

=) P (A)=6/12 =1/2

b) let B be the probability for the sum as 11.

B={(6,5) , (5,6)}

n (B)=2

=) P (B) = n(B)/n (S)

=) P (B) =2/11

c) let C be the probability of getting sum 13

not possible

so, P (C)=0
