could someone please help me with this question ?
a lottery has 45 balls (1 to 45)
6 balls are randomly generated each week
you can choose the amount of numbers you want to play
you can pick 1 number and it pays 6 to 1 if your 1 number comes up in one of the 6
I decide to bet £1 on 3 numbers 16 17 23 , which pays 600 to 1 ,
what are the real odds of hitting all 3 of my numbers and bagging
2. what is the ev for this game?
Since we have 45 unique balls, each time we pick one, the chances of drawing the others increases. So the probability of drawing all three is (3/45) * (2/44) * (1/41). As assuming we pick one of your 3 numbers on the 1st try, we have the other two remaining out of 44.
