Question

I need a solution to these two questions guys!!!!! Only serious answers

Answer 1

1.

`A\cup B=\{2,3,4,5,6,7,8,9,10,11,12,13\}\\\\A\cap B=\{5\}`

2.

`\overline{\overline{\Omega}}=10\\\\\overline{\overline{B}}=5\quad\implies\quad P(B)=\frac5{10}=\frac12\\\\\overline{\overline{C}}=6\quad\implies\quad P(C)=\frac6{10}=\frac35\\\\\overline{\overline{B\cup C}}=5+3=8\quad\implies\quad P(B\cup C)=\frac8{10}=\frac45\\\\ \overline{\overline{B\cap C}}=3\quad\implies\quad P(B\cap C)=\frac3{10}`
