Teams P and Q are involved in a game of football. What is the probability that the game ends in a draw?

A.

2/3

B.

1/2

C.

1/3

D.

1/4

Correct Answer: 1/4

Explanation

P (games end in draw) => Team P wins and Q wins P(P wins) = 1/2 P(Q wins) = 1/2 Therefore P (games ends in draw) = 1/2 x 1/2 = 1/4

P (games end in draw) => Team P wins and Q wins P(P wins) = 1/2 P(Q wins) = 1/2 Therefore P (games ends in draw) = 1/2 x 1/2 = 1/4
