Prove that if E and F are independent events, then so are the events E and F'.

Determine P(E|F) A die is thrown three times, E : 4 appears on the third toss, F : 6 and 5 appears respectively on first two tosses

Two dice are thrown together and the total score is noted. The events E, F and G are 'a total of 4', 'a total of 9 or more', and 'a total is divisible by 5', respectively. Calculate P(E), P(F) and P(G) and decide which pairs of events, if any, are independent.

E and F are two independent events. The probability that both E and F happen is 1/12 and the probability that neither E nor F happens is 1/2. Then
