1. At the horse races, the chances of a horse winning is expressed as odds against. In the first race, the different odds against winning for three of the horses are as follows: Horse 1 at 7:2, Horse 2 at 4:1 and Horse 3 at 11:3. o What are the odds in favour of Horse 2 winning the race? o Which horse has the better probability of winning the race? 1. In the game of Bingo, there are 75 balls numbered from 1 to 75. Using the related formula, what is the probability that you select: o a ball that is an even number? o a ball that is less than 16 or greater than 60? o a ball that is even and then a ball that is odd?
