In a lotto, a player picks a selection of 6 numbers from the numbers 1 to 45. To determine the winners 8 numbers are chosen at random - the first 6 are designated as the winning numbers, and the other 2 as supplementary numbers.
Division 1: 6 winning numbers
Division 2: 5 winning numbers and 1 supplementary
Division 3: 5 winning '
Div 4: 4 winning '
Div 5: 3 winning ' and 1 supplementary
Find the number of combinations which satisfy each of the divisions, and hence the probabilities of winning each of the five divisions.
