2/ 36
I hope it helps you

Answer 2

Here is your answer

All possible outcomes in throwing a pair of dice are $6^{2}$ = 36

Since, 2 will not come as outcome

So, pair of outcomes which shows the sum 7 are: (1,6); (3,4); (4,3); (6,1)

Favourable outcomes= 4

Total outcomes= 36

P (E) = ${4}/{36}$

= ${1}/{9}$
