1. Amy rolls a 6-sided die 10 times. What is the probability that 3 specified rolls are 6s and none of the others is an 6? answer 0.0013 2. Amy tosses 90000 biased coins. Each coin comes up heads with probability 0.7. What is the probability that exactly 4 of the last 9 coins come up heads? answer 0.0735 3. Amy rolls a 6-sided die 20000 times. What is the probability that exactly 4 of the last 12 rolls are...
1) What is the probability of rolling exactly two 4’s during four rolls of the dice? 2) What is the probability of getting a total of at least two 4’s during four rolls of the dice?
Suppose you are rolling a fair four-sided die and a fair six-sided die and you are counting the number of ones that come up. What is the probability that both die roll ones? What is the probability that exactly one die rolls a one? What is the probability that neither die rolls a one? What is the expected number of ones? If you did this 1000 times, approximately how many times would you expect that exactly one die would roll...
A fair die has four faces numbered one to four. What is the probability of rolling a two exactly three times in ten rolls of the die?
A six-sided die is to be rolled three times. Assume the rolls are independent and that the die is fair. - The probability that all three rolls result in an even number is: A) 1.0 B) 0.75 C) 0.25 D) 0.125 - The probability that at least one of the rolls is an even number is: A) 0.125 B) 0.333 C) 0.750 D) 0.875 - The events A = exactly two of the rolls are even and B = exactly...

fou-369850 Question Beth is performing an experiment to check if a die is fair. She rolls the die 5 times and records the sequence of numbers she gets. Which of these is an outcome of this experiment? Select all correct answers. Select all that apply: Rolling a die Rolling a die five times Rolling the sequence 1, 1,2, 1,6 Rolling five 4's Rolling the sequence 1, 1,2
In a game of repeated die rolls, a player is allowed to roll a
standard die up to n times, where n is determined prior to the
start of the game. On any roll except the last, the player may
choose to either keep that roll as their final score, or continue
rolling in hopes of a higher roll later on. If the player rolls all
n times, then after the nth roll, the player must keep that roll
as...
A fair -sided die is rolled four times. What is the probability that all four rolls are 5? Write your answer as a fraction or a decimal, rounded to four decimal places.
