There are 400 red gumballs, 200 white gum balls, 300 black and 100 green. You have three dimes (each piece is worth 10 cents). What is the probability of getting no black gumballs? ******MUST USE THE FORMULA OF NONE = 1-ALL*****
Homework Answers
Total gumballs = 400+200+300+100 = 1000
black gumball = 300
Probability of getting one black gumball out of 3 =
Probability of getting two black gumball out of 3 =
Probability of getting all three black gumball out of 3 =
Probability of getting no black gumball in three dimes = 1 - [ P(1) +P(2)+P(3) ]

An urn has 3 red balls, 4 white balls and 2 black balls. Each red ball is worth $2 and and each black ball is worth −$3 (note the negative sign). White balls have no value. You draw four balls at random from the urn. (a) What is the size of the sample space? (b) What is the probability that the total value of the four balls is $3?

Suppose that you have an urn with 500 balls, 100 of which are red and 400 are black. (a) You sample 10 balls at random with replacement. What is the probability that at least 2 of them are red? (b) You sample 10 balls at random without replacement. What is the probability that none of them are red? (expression only)

There are 3 white, 3 red and 5 black balls in a box. By chance, three balls are taken out from the box. The person wins 1 dollar when taking out a white ball but loses 1 dollar when taking out a red ball. X is an event, describing the amount of money that was won (lost) in one try. What values does X have and what are the probabilities of those values? What is the probability that the money...
