A die is continuously rolled until the total sum of all rolls exceeds 275. What is the probability that at least 70 rolls are necessary?
Please show work so i can understand it. Thank you! (1 point) A die s continuously rolled until the total sum of all rolls exceeds 175 What is the probability that at least 55 rolls are necessary? 0.1423
A fair die is rolled 12 times. What is the expected sum of the 12 rolls?
A fair die is rolled 5 times. What is the probability that a 2 is obtained on at least one of the rolls? Round your answer to three decimal places. (If necessary, consult a list of formulas.)
Two dice are rolled repeatedly until the sum of the two numbers rolled is 10 or more. a) What is the probability that exactly 5 rolls are needed? (Count each time you roll the dice as one roll). b) What is the probability that more than 5 rolls are needed? c) Find the expected number of rolls.
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...
We roll a die until the sum of points obtained exceeds 350. Approximate the probability that we will roll more than 120 times.
A six-sided die is rolled 500 times. Use the CLT to approximate the probability that the sum of the rolls exceeds 1800.You’ll need to know the expectation (μ) & variance (σ2) of a single roll.
In an experiment, a die is rolled continually until a 6 appears, at which point the experiment stops. What is the sample space of this experiment. Let En denote the even that n rolls are necessary to complete the experiment. What points of the sample space are contained in En? Describe the event (UnEn)
#6-2 points A fair die is rolled 9 times. What is the expected sum of the 9 rolls? 42
