Question 982878: A box contains 9 green, 1 red, 5 yellow, 6 blue, and 7 purple marbles. Four marbles are drawn from the box simultaneously.
a) What is the probability that none of the marbles are purple?
b)What is the probability that all four buttons are different colors?
c)What is the probability that at least three of the marbles are green?
a. The probability that the first marble is not purple times the probability the second marble is not purple given that the first marble is not purple times the probability that the third marble is not purple given that the first and second marbles are not purple times the probability the fourth marble is not purple given that the first, second, and third marbles are not purple. If is the number of non-purple marbles, and is the total number of marbles, then:
b. Zero. There is no chance of selecting a button of any color from a bag of marbles.
