We have total 30 balls which are grouped by size and color as follows. What is the probability that a randomly chosen ball is not large or not yellow? Large Small Red 5 5 Blue 4 6 Yellow 7 3
Large | Small | |
Red | 5 | 5 |
Blue | 4 | 6 |
Yellow | 7 | 3 |
P(a randomly chosen ball is not large or not yellow) = 1 - P(a randomly chosen ball is large and yellow)
= 1 - 7/30
= 23/30

Urn A contains 7 yellow balls and 3 red balls. Urn B contains 10 yellow balls and 7 red balls. Urn C contains 12 yellow balls and 4 red balls. An urn is picked randomly (assume that each urn is equally likely to be chosen), and then a ball is picked from the selected urn. What is the probability that the chosen ball came from urn B, given that it was a yellow ball?
Suppose that we have a box containing 3 red balls and 4 blue balls, if two balls are selected randomly from the box in succession without replacing the first, what is the probability that both balls are in the same color ?
1) Suppose a bag contains 50 red balls, 30 green balls and 20 blue balls. (a) If you draw 2 balls at random without replacement, what is the probability that they are red and green? (b) If you draw 3 balls at random without replacement, what is the probability that all 3 are of different colour? (c) If you draw 3 balls at random without replacement, what is the probability that you draw at least 1 red ball? 2) A...
3. A box contains 10 red balls, 6 blue balls, and 4 white balls. We have taken 2 balls from the box. What are probabilities that we have taken c) one red ball and one white ball b) at least one blue bal a) 2 blue balls d) no one red ball
Please need help right away One container contains one blue ball and four red balls. A second container contains three blue balls and two red balls. An experiment is performed in which one of the two containers is chosen at random and then two ball are randomly chosen from it, one after the other without replacement. a) What is the total number of outcomes of this experiment? A 25, B 19, C 10, or D 24 b) What is the...
Four balls are to be randomly chosen from an urn containing 4 red, 5 green, and 6 blue balls. 1. Find the probability that at least one red ball is chosen? 2. Given that no red balls are chosen, what is the probability that there are exactly 2 green balls among the four balls chosen.
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?
Suppose there is an urn containing 5 red, 4 white, and 11 blue balls. We drawn six balls from the urn (no replacement) (a) Find the number of ways (not the probability) of choosing a red ball, then a blue ball, then exactly 2 white balls, and finally exactly 2 blue balls. (b)Find the number of ways of choosing 2 red balls initially , then at least 3 blue balls, then a green ball. (c) Find the number of ways...
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?
A bowl contains 6 blue balls and 5 green balls which share no difference other than color. Suppose 3 balls are randomly selected. What is the probability that 2 blue balls and 1 green ball are obtained?
