A die is tossed twice. What is the probability of getting a sum of 10 ?

Options

  1. A118\frac{1}{18}
  2. B16\frac{1}{6}
  3. C112\frac{1}{12}
  4. D512\frac{5}{12}

Correct answer

C. 112\frac{1}{12}

Step-by-step solution

Sample event =(4,6),(5,5),(6,4)=(4,6),(5,5),(6,4), n(E)=3n(\mathrm{E})=3 Sample space =6×6,n(s)=36p(E)=n(E)n(s)=336=112.=6 \times 6, n(s)=36p(\mathrm{E})=\frac{n(\mathrm{E})}{n(s)}=\frac{3}{36}=\frac{1}{12}.
