उत्तर
If E and F are two independent events such that P(E) = `2/3`, P(F) = `3/7`, then `P(E//barF)` is equal to `bbunderline(2/3)`.
Explanation:
P(E) = `2/3`,
P(F) = `3/7`
`P(E//barF) = ((P(E ∩ barF))/(P(barF)))`
= `(P(E) xx P(barF))/(P(barF))` ...(∵ E and F are independent events)
= `P(E) ...[∴ P(E ∩ barF) = P(E).P(barF)]`
= `2/3`
