A random number generator selects three numbers independently, each from 1 through 10. Find the probability of the event.

Question

One number is 2, 4, or 6, and the other two numbers are 3, 5, 7, or 9.

Answer 1

Can the digits be used more than once?

Yes, they can be used more than once

(sampling with replacement):

3/10 * 4/10 * 4/10 = 48/1000 = 6/125 = 0.048

No, they can NOT be re-used once selected..

(sampling without replacement)

3/10 * 4/9 * 3/8 = 36/720 = 1/20 = 0.05
