2. A fair red die and a fair blue die are rolled 2 times each. What is the probability of the product of numbers on the red die is less then the sum of numbers on the blue die?
2. A fair red die and a fair blue die are rolled 2 times each. What is the probability of the product of numbers on the red die is less then the sum of numbers on the blue die? -Ive already posted this question but the answer given didn't explain how to calculate the number of successful cases. I know the total possible cases is 6*6*6*6=1296, but how do you calculate the number of successful cases?
If a red and a blue fair six sided die are rolled what is the probability the result is 8 or divisible by 3? Please try to be as specific as possible with each step. I've how the get the answer but I really don't get how they do it.
A fair die is rolled 12 times. What is the expected sum of the 12 rolls?
#6-2 points A fair die is rolled 9 times. What is the expected sum of the 9 rolls? 42
A fair die is to be rolled 20 times. Find he expected value of the number of times (a). 6 appears. (b). 5 or 6 appears. (c). An even number appears. (d). Anything else but 6 appears. please explain the step
7. (3 points) Given a fair 6-sided die. Each time the die is rolled, the probabilities of rolling any of the numbers from 1 to 6 are all equal. 1) If it is rolled once and let A be the event of rolling a number larger than 3 and B be the event of rolling an odd number. What is P(AV B)? 2) If it is rolled three times, what is the probability that the same number shows up in...
Problem 8 A fair die is rolled 10 times. What is the probability that the rolled die will not show an even number?
A standard six sided die is rolled 11 times. What is the expected value of the number of times an odd number will be rolled. Do not round your answer.
Question 5: You are given a fair red die and a fair blue die,
and roll both dice uniformly at random and independently of each
other. Define the events A = “the sum of the results is at least
9”, B = “at least one of the two rolls results in a 2”, C = “at
least one of the two rolls results in a 5”. • Determine Pr(A),
Pr(B), and Pr(C). • Determine Pr(B | C). • Are the...
