Two coins are tossed once. `P(E//F)` in each of the following: `E=` Tail appears on one con, `F=` one coin shows head `E=\ ` No til appears, `F=` No head appears,

Explanation

The sample space `S` of an event where two coins are being tossed together is given by,

`S={(H,H),(H,T),(T,H),(T,T)}`

Here, the number of elements in the sample space `S` is,

`n(S)=4`

`(i)` `E` stands for "tail appears on one coin", i.e.,

`E={(H,T),(T,H)}`

And, `F` stands for "one coin shows head", i.e.,

`F={(H,T),(T,H)}`
