Question

Two dice are thrown simultaneously at random .find the probability of getting sum of eight

Answer 1

Explanation:

={1,1},{1,2},{1,3},{1,4},{1,5},{1,6}

{2,1},{2,2}{2,3}{2,4}{2,5}{2,6}

{3,1}{3,2}{3,3}{3,4}{3,5}{3,6}

{4,1}{4,2}{4,3}{4,4}{4,5}{4,6}

{5,1}{5,2}{5,3}{5,4}{5,5}{5,6}

{6,1}{6,2}{6,3}{6,4}{6,5}{6,6}

n(P)=36

event A:getting sum of eight

A={2,6}{3,5}{4,4}{5,3}{6,2}

n(A)=5

Answer 2

Answer:

5 is the probability of getting sum of 8
