Question

PLEASW HELP ME THIS IS LIKE CHINESE TO MEEE

Answer 1

It is given that

`P(A)=(1)/(3)`

`P(B)=(2)/(5)`

`P(A\cap B)=(3)/(5)`

According to the union formula:

`P(A\cup B)=P(A)+P(B)-P(A\cap B)`

`P(A\cup B)=(1)/(3)+(2)/(5) -(3)/(5)`

`P(A\cup B)=(1)/(3)+(2-3)/(5)`

`P(A\cup B)=(1)/(3)-(1)/(5)`

`P(A\cup B)=(5-3)/(15)`

`P(A\cup B)=(2)/(15)`

Therefore the value of P = (A ∩ B) is
`\bold{(2)/(15)}`.
