Explanation / Answer

a)

no of digits = 10

no of possible ways to draw three digits from 10 digits when order is important = 10*9*8 = 720

probability of winning a pick 3 lottery if you buy a single ticket = 1/720 = 0.0014

b)

probability of not winning a pick 3 lottery if you buy a single ticket = 1 -1/720 = 1-0.0014 = 0.9986

c)

no of possible drawings that are not in 10 slections in tickets = 720-10 = 710

probabiltiy of not winning on each of 10 different tickets if each ticket has a single three-digit selction = 710/720 = 0.9861
