Suppose you have a bag with ten balls in it, and each ball has a digit printed on it:
0,1,2,3,4,5,6,7,8,9. So there is one ball for each of the ten digits 0-9.
a) If you pull out three balls and set them aside, what is the probability that you pull out the
numbers “5”, “0”, and “4”, in that order? (“5” is your first pull, “0” is your second, and “4” is
your third).
b) For part (a), what is the probability that your three numbers consist of “5”, “0”, and “4” in
any order? Express your answer as a fully reduced fraction.
c) Suppose instead you take a ball out, record its value, then return it into the bag, then repeat
this process three total times. What is the probability that you will select the 5, the 0, and the 4,
in that order?
d) In part (c), what is the probability that your three selections consist of the number 4 twice,
and the number 8 once, in any order?

You have 8 balls. Each ball is labeled 1,2,3,4,5,6,7,8 and are inside of one bag. Imagine you randomly take 3 balls from the bag. What is the probability that the product of the three numbers on the balls you select is even?
A bag contains 3 red and 1 orange ball. You pick two balls from the bag with replacement. What is the probability that you will get two orange balls? 1/4 0 1/12 1/16
A bag contains 3 red and 1 orange ball. You pick two balls from the bag with replacement. What is the probability that you will get two orange balls?
A bag contains 80 balls numbered 1, . . . , 80. Before the game starts, you choose 10 different numbers from amongst 1, . . . , 80 and write them on a piece of paper. Then 20 balls are selected (without replacement) out of the bag at random. (a) What is the probability that all your numbers are selected? (b) What is the probability that none of your numbers is selected? (c) What is the probability that exactly...
My daughter, B., has a ball pit with 500 balls. There are 100 purple balls and 400 balls that are not purple. Part A: B. puts on her reindeer eye mask so she can’t see, and she randomly throws six balls outside the ball pit, one at a time. What is probability that she throws out exactly 3 purple balls, as in the photo below? (The order doesn’t matter and the color of the other three balls doesn’t matter, as...
PLEASE HELP WITH 2 AND 3!! THANK YOU:) 2. How many 4-digit numbers can be formed from the digits 2,3,4,5,6,7,8 if: i) Each digit may be used only once in each number? ii) Each digit may be used repeatedly in each number? 3. A bag contains five red balls numbered 1,2,3,4,5 and nine green balls numbered 6,7,8,9,10,11,12,13,14. If a ball is drawn at random what is the probability that: i) The ball is red and odd-numbered. ii) The ball is...
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...
One bag contains 4 white and 2 black balls. Another contains 3white and 5 black balls. One ball is drawn from each bag. Find theprobability that both are of same colour.
Michael has a box of colored balls. It contains two red balls, two green balls, two yellow balls, and five blue balls. Michael draws a ball at random from the box Let R denote the event that the ball he draws is red, and let B denote the event that the ball he draws is blue. What is Pr(R|B)? What is Pr(R|B′)? Enter your answers as whole numbers or fractions in lowest terms. A bag contains four 1-dollar bills, three...
There is a bag full of balls numbered 1 to k. As you reach in to pick one, he notes that they are not all equally likely because of magic: ball 1 is least likely to be chosen, with probability c, where c is some constant. Ball 2 has probability 2c, Ball 3 has probability 3c, . . . , Ball k - 1 has probability (k - 1)c, and Ball k has probability kc. What is the expected value...
