I think I have a very good idea for a,b,c but am stuck with the rest. Thank you for your help!

A four-digit number is formed by randomly drawing four numbers from the set {0, 1, 2, 3. 4. 5. 6. 7. 8, 9},without replacement. The digits are written down in the order they are drawn. Note: In this problem, we will not consider numbers beginning with 0 to be four-digit numbers. If I] is drawn rst, it is replaced, and we randomly draw again, until we get a number that is not 0. We will dene the following events: A = the four-digit number is even. B = the four-digit number is divisible by 4. C = the four-digit number is divisible by 5. Find: a. pm) 13. p03] c. pm] :1 HAIR} e. P(B|A] r. P[B u c)
