Natalia Case · Answer 1

There are 8 numbers for the computer to choose from.

So the probability of choosing a particular number is 1/8.

The first number can be any one of the 8.

The second and the third must be the same as the first, with probability 1/8.

Therefore the probability that all three numbers are the same

= (1/8) (1/8) = 1/64 [ player will win a prize ]

(=0.03125)
