![A=15 B=10 A∪B=A+B−A∩B=20 A∩B=15+10−20=5 p(A∩B)=((A∩B)/(A∪B))=(1/4)](https://www.tinkutara.com/question/Q134125.png)
$${A}=\mathrm{15} \\ $$$${B}=\mathrm{10} \\ $$$${A}\cup{B}={A}+{B}−{A}\cap{B}=\mathrm{20} \\ $$$${A}\cap{B}=\mathrm{15}+\mathrm{10}−\mathrm{20}=\mathrm{5} \\ $$$${p}\left({A}\cap{B}\right)=\frac{{A}\cap{B}}{{A}\cup{B}}=\frac{\mathrm{1}}{\mathrm{4}} \\ $$
