Question

A dice throwen twice what will be the probability that the sum on the faces is_ (a) 9 (b)13​

Answer 1

Answer: a-9

because the sum of the largest number(6) twice is 12 and the other option is 13

Answer 2

Answer:

• the sum 9 may be (1,8) (2,7) (3,6) (4,5) (5,4) (6,3) (7,2) (8,1) . => favourable outcomes =>8 & total outcomes => 36.

p(e)=> 8/36 => 2/9.

• the sum is 13 but this cannot possible because the total sum is (6,6)=>12

so favourable outcomes =>0.

total outcomes =>36.

p(e) =>0/36. =>0.
