You have two bags each containing six balls. The first bag contains balls numbered 1 to 6 and the second bag contains balls numbered 7 to 12. A ball is drawn out of bag one and another ball is drawn out of bag two. What are the chances that at least one of the balls drawn out is an odd numbered ball?

Ans: 3 in 4.

The possible combinations of drawing the balls are
Odd – odd

In a game of eight players lasting for 90 minutes, four reserves alternate equally with each player. This means that all players, including the reserves, are on the pitch for exactly the same length of time. For how long is each player on the pitch?

Ans: 60 minutes

Total time for 8 players = 80 x 90 = 720 minutes.

However, as 12 people (8 + 4) are on the pitch an equal length of time, they are each on the pitch for 60 minutes (720 ÷ 12).
