Question

Probability

1- In a game of Craps (a gambling game where two dice are rolled at a time), rolls of 2 and 12 are both known as “craps” and end the round. Why might these rolls have been chosen as round ending (and often losing) rolls?

2- I am considering buying raffle tickets and know the odds of winning are 1 in 10. If the ticket I have is a winner, there is a 1 in 4 chance that it is for a new car. what are the chances that if I buy a ticket I have won a car?

a) 0.01

b) 0.025

c) 0.1

d) 0.25

e) No telling. It's random.

Explanation / Answer

Because there are only 1 cases each to get sum of 2 and 12 => (1,1), (6,6)

Since that it have probability of 2/36 = 1/18 which is pretty low Thats why they are used to end the game

2) (1/10)*(1/4) = (1/40) = 0.025
