Answer:
Probability (A sum of 10)=0.1025
Step-by-step explanation:
[tex]\begin{center}\begin{tabular}{ c c c c c c c } Spots & 1 & 2& 3 & 4& 5 & 6 \\ \\Prob & 0.10 & 0.15& 0.20 & 0.25& 0.20 & 0.10 \end{tabular}\end{center}[/tex]
To find the Probability the sum is 10, we can either have
i. a 4 and a 6
ii. a 5 and a 5
Pr (A AND B) = Pr (A) x Pr(B)
Pr (A OR B) = Pr (A) + Pr(B)
Probability (A sum of 10) = Pr(getting a 4 AND a 6) OR Pr(getting a 5 AND a 5)
=(0.25 x 0.25)+(0.20 x 0.20)
=0.0625+0.04
=0.1025
