Suppose that I have a bag containing 18 quarters, and 12 pennies. Two coins were selected from the bag at random, without replacement. First, draw a tree diagram showing the different possible outcomes, including their respective probabilities. Then, answer the following questions: please USE TI 83/84 CALCULATOR FOR COMPUTING What is the probability that both of the coins were quarters? What is the probability that one of the coins was a quarter and the other was a penny?
A box contains seven marbles. Four of them are red and 3 of them are green. You reach in and choose three at random without replacement. Define a random variable X as: X = the number of red marbles selected. (a) What are the possible values X can take on? (i.e. give Im(X)) (b) Find P(X = x) for all x in Im(X). (c) Make a table for the probability distribution of X as shown in lecture. (Leave probabilities as...
7.) A bag contains five marbles of which two are red, two are green and one is blue. You will randomly draw two marbles from the bag without replacement. Construct a decision tree for all the possible outcomes of this random experiment and use it to determine the probability that the two marbles are of different colors. (You may draw the decision tree on a sheet of paper and submit a photo of it as a separate file or an...
