There are 4 red balls, 5 green balls, and 6 blue balls inside a box.
a. If one balls is selected at random, what is the probability that the ball is green color?
b. If one ball is selected at random, what is the probability that the ball is not red?
There are 4 red balls, 5 green balls, and 6 blue balls inside a box. a....
An urn contains 5 red, 6 blue, and 8 green balls. A. if a set of 3 balls is randomly selected, what is the probability that each of the balls will be the same color? b. if a set of 3 balls is selected but each time a ball is drawn the color is noted and the ball returned, what is the probability the balls will be the same color?
A box contains 6 red balls, 3 green balls, 7 blue balls, and 2 white balls. If two balls are two be selected with replacement, find the probability of selecting a red and blue ball. Oa. 0.10 O b.0.15 Oc. 0.13 Od.0.08
(+5)* 6. Suppose that a box contains 2 red balls, 3 white balls, and 4 blue balls. Suppose also that balls are selected from the box one at a time, at random, without replacement. What is the probability that a) all white balls will be obtained in a row? b) both end balls are blue?
6. A box contains 30 red balls, 30 white balls, and 30 blue balls. If 10 balls are selected at random, without replace- ment, what is the probability that at least one color will be missing from the selection? 6. A box contains 30 red balls, 30 white balls, and 30 blue balls. If 10 balls are selected at random, without replace- ment, what is the probability that at least one color will be missing from the selection?
An urn contains 5 blue balls, 5 white balls, 5 red balls, and 5 green balls. Larry is selecting 4 balls at random one after the other without replacement. What is the probability that at least one of the selected balls is blue?
A box contains 6 red balls and 5 green balls. Three balls are selected at random from the box with replacement. What is the probability that exactly two of the three balls are green?
An urn contains 6 red, 9 green, and 11 blue balls. The following is repeated 3 times: a ball is selected from the urn at random and removed (called “sampling without replacement”). Give your answers to 3 significant digits. (a) What is the probability that all 3 selected balls are the same color? (b) What is the probability that all 3 selected balls are different colors? (c) Repeat part (a) assuming “sampling with replacement”. That is, the following is repeated...
There are 5 red, 20 green, and 10 white balls in a box. A ball is chosen at random and it is noted if it is red or green. The process repeats, returning the ball 8 times. The probability that a red or green ball is selected 4 times is
3. There are 6 red and 4 blue balls inside an urn. Three balls are selected at random without replacement. Find the probability of the event that more red balls are selected.
1. An urn initially contains 6 red and 8 green balls. Each time a ball is selected, its color is recorded, and it is replaced in the urn along with 2 other balls of the same color. Compute the probability that: (a) The first 2 balls selected are green and the next 2 are red? (b) Of the first 4 balls selected, exactly 2 are green? (c) If the second ball selected is green, what is the probability that the...
