1. a. The probability of getting a 0 is 0, as there are no 0s on a die.
b. There are four composite numbers on a die: 4, 6, 8, and 9. Therefore, the probability of getting a composite number is 4/6 or 2/3.
c. There is one 3 on a die, so the probability of getting a 3 is 1/6.
d. The numbers divisible by 3 on a die are 3 and 6. Therefore, the probability of getting a number divisible by 3 is 2/6 or 1/3.
2. a. There are 13 spade cards in a standard deck, so the probability of getting a spade is 13/52 or 1/4.
b. There are four number 9 cards in a standard deck (9 of hearts, 9 of diamonds, 9 of clubs, and 9 of spades), so the probability of getting a number 9 is 4/52 or 1/13.
c. There are two red Queens in a standard deck (Queen of Hearts and Queen of Diamonds), so the probability of getting a red Queen is 2/52 or 1/26.
d. There are two black Kings in a standard deck (King of Spades and King of Clubs), so the probability of getting a black King is 2/52 or 1/26.
3. a. There are no green balls in the bag, so the probability of getting a green ball is 0.
b. There are 7 white balls in the bag, and a total of 18 balls. Therefore, the probability of getting a white ball is 7/18.
