Thank you for the assistance.

Explanation / Answer

A. There are 1000 different outcomes - from 10 * 10 *10. There are 10 possibilities for the first number, 10 forthe second, and 10 for the 3rd - which makes 1000 possible. B. If you pick 1 ticket, the probability is1/1000. That is 1 outcome out of the 1000. C. If you have 3 different tickets, the probability isthen 3/1000 (3 outcomes out of the 1000). The drawing you have is just a simple probabilitydiagram. the sign (~) means not. so the area outsidethe circle is designated as Not B, which is B not occuring. P(B) + P(~B) has to equal 1. Either B can happen or not, sothe probability of that combined is 1.
