You roll a balanced die two times. Is the second roll independent of the first roll?

Expert Solution

Yes it is. The die has no memory.

So the outcome of the first roll does not influence the second, or later rolls.

This only works if a die is perfectly balanced - which it never is, and that's why dice are changed every now and again.

And the surface on which it is rolled must not interact with the die (like being slightly wet or sticky or static).

Yes it is. The die has no memory.

PROJECT C Roll a 6-sided die 800 times. If you do not desire to roll a die manually, STATDISK can be used to simulate the process. To use STATDISK, go to “Data” at the top of the STATDISK window, and then choose “Dice Generator”. The “Dice Roll Random Sample Generator” window will appear. Then in that window, put 800 in for “Sample Size”, put 1 in for “Num Dice”, and put 6 in for “Num Sides”. Please disregard the “Random...

What is the probability that, if you roll a balanced die twice, that you will get a "1" on both dice?

John and Mary each have a balanced die. They each roll their die repeatedly; once someone rolls a ‘6’, he/she stops rolling. Let Y1 = the number of times John rolls and Y2= the number of times Mary rolls. (a) Find P(Y1 + Y2 =5). (b) Find P(Y1 = Y2).

Consider the following experiment: we roll a fair die twice. The two rolls are independent events. Let’s call M the number of dots in the first roll and N the number of dots in the second roll. (a) What is the probability that both M and N are even? (b) What is the probability that M + N is even? (c) What is the probability that M + N = 5? (d) We know that M + N = 5....

(1) For the random experiment “toss a fair coin twice and then roll a balanced die twice”, what’s the total count of the sample space? Let A be the event {both tosses show HEADs and both rolls show sixes}, B = {both tosses show the same side of the coin and both rolls show the same number}, C = {both tosses show the same side OR both rolls show the same number} and D = {the 1st roll of the...

Problem #1 You ask your graduate student to roll a die 5000 times and record the results. a) Give the expected mean and standard deviation of the outcome. P= 1/6 , Q= 5/6 NP= 5,000 NP X P= 5,000 *1/6 = 5,000/6 SD: Square root(5,000 * 1/6 * 5/6) = Square Root b) The die roll experiment is repeated (though with a different graduate student – for some reason your previous student went to work with a different advisor). However in...

26. You roll an eight-sided die five times and get a four every time. You suspect that the die favors the number four. The die maker claims that the die does not favor any number. a. Perform a simulation involving 50 trials of rolling the actual die and getting a four to test the die maker’s claim. Display the results in a histogram. b. What should you conclude when you roll the actual die 50 times and get 20 fours?...

Three people, X, Y, Z, in order roll an ordinary die. The first one to roll an even number wins. The game continues until someone rolls an even number. Determine the probability that either Y or Z will win.

Suppose that we roll a die 166 times. What is the approximate probability that the sum of the numbers obtained is between 544 and 606, inclusive. (if possible, could you explain the steps/ state theorems used). Thank you :)
