4/7


Let Pa, Pb and Pc be the probability of them respectively. We have then:
Pa=2Pb
Pb=2Pc
If Pc=P, then Pa=4P and Pb=2P
P+2P+4P=1 => P=1/7
Pa=4*1/7=4/7

Three men — conveniently named A, B, and C — are fighting a duel with pistols. It's A's turn to shoot.

The rules of this duel are rather peculiar: the duelists do not all shoot simultaneously, but instead take turns. A fires at B, B fires at C, and C fires at A; the cycle repeats until there is a single survivor. If you hit your target, you'll fire at the next person on your next turn.

For example, A might shoot and hit B. With B out of the picture, it would be C's turn to shoot — suppose he misses. Now it's A's turn again, and he fires at C; if he hits, the duel is over, with A the sole survivor.

To bring in a little probability, suppose A and C each hit their targets with probability 0.5, but that B is a better shot, and hits with probability 0.75 — all shots are independent.

What's the probability that A wins the duel?

A Cricket Team needs to score 7 runs in last 2 balls to win the match.What is the probability that the team wins the match?
Assume that:
-There were no wide balls or no balls bowled in these 2 balls.
-No wicket has fallen in these 2 balls.
-No overthrows or extra runs were scored in these 2 balls.
- In case if run(s) are scored on any of these 2 balls it can only be one of these values: 1,2,3,4 & 6
This also implies that it's quite possible that zero runs are scored on a particular ball
