Question 809843: 1.Suppose an urn contains 8 red,5 white and 7 blue marbles.
a.If 3 marbles are drawn at random from the urn with replacement,what is the probability that three marbles are red? Give answer as a reduced fraction.
b.Suppose an urn contains 8 red,5 white and 7 blue marbles.if 3 marbles are drawn at random from the urn without replacement,what is the probability that three marbles are red? Give answer as a reduced fraction.
c.If 3 marbles are drawn at random from the urn with replacement,what is the probability that three marbles are the same color?Give answer in a reduced fraction.
2.Suppose you draw three cards at random from a deck without replacement.What is the probability that they are not all three face cards? Give your answer as a reduced fraction

a.If you roll two fair dice,one red and one green,what is the probability of getting a 2 on the red die and a 3 on the green die? Give answer in a reduced fraction.
b.If you roll two fair dice,one red and one green,what is the probability that the sum of the two dice is 5? Give answer in a reduced fraction.
c.If you roll two fair dice,one red and one green,what is the probability of getting a least one 6 on the two dice? Give answer in a reduced fraction
Answer by edjones(8007)   (Show Source):
You can put this solution on YOUR website! 2)4*3=12 face cards in the deck.
12C3/52C3
=220/22100
=11/1105 Probability that they are all face cards.
.
1 - 11/1105
= 1094/1105
