A random variable and a probability distribution?
The number of 6s in 37 rolls of a loaded die and binomial.
What is the probability of rolling 2 sixes in a row with a single die?
It is a certainty. If the die is rolled often enough, the probability that two consecutive rolls show a six is 1.
What is the probability that none of the rolls is a six?
It depends on what size die you use, what its labels are and how many rolls you make. For example using a standard six-sided die and one roll, the probability of no sixes is 5/6 or ~0.83; the probability of no sixes with 25 rolls is less than 0.01 or 1%. If you used a standard d3 (three-sided die) then the probability will always be 1 or 100%, since rolling a six is impossible; but if every side has '6' on it the probability is 0, since every roll must be a 6.
If you roll a die 300 times how many times would you expect to get a 5?
If George rolls the die 300 times, how many fives will he roll?
18 rolls is what percent 400 rolls?
