If you roll a die 30 times how many times should you expect to roll a number less than 3?
The expected number of rolls under 3 is the number of rolls times the probability of rolling less than 3. So: E(rolls less than 3 out of 30) = 30 * 1/3 = 30/3 = 10
Why Based on the experimental probability predict the number of times that you will roll a 5 if you roll the number cube 300 times.?
The expectation is 50 times.
If i roll a die 90 times how many times can i expect to roll a 6?
pr(six) = 1/6 → expected 6s in 90 rolls = 1/6 × 90 = 15
If you roll a dice 60 times what is the probability that you will roll a 4?
Pr(You roll a four in 60 rolls) = 1 - Prob(No fours in 60 rolls) = 1 - [Prob(Not 4 in a roll)]60 = 1 - (5/6)60 = 0.999982 ie 99.9982 per cent
If a dice is rolled 90 times what is the sum of the first and second roll expected to be on average?
If a DIE (not dice) is rolled 90 times, the expected value of the sum of the first and second rolls is 7 if you assume that the die is fair. It does not matter how many times you roll the die, as long as it is at least 2.

If you roll a die 30 times how many times should you expect to roll a number less than 3?

You roll a number cube 150 times about how many times would you expect to roll 3?
Possible outcomes of one roll = 6Successful outcomes = 1Probability of success on each roll = 1/6Expectation in 150 rolls = (1/6) x (150) = 25 times
Why Based on the experimental probability predict the number of times that you will roll a 5 if you roll the number cube 300 times.?
The expectation is 50 times.

How many single rolls equal a double roll?
Two.
If you roll a dice 60 times what is the probability that you will roll a 4?
Pr(You roll a four in 60 rolls) = 1 - Prob(No fours in 60 rolls) = 1 - [Prob(Not 4 in a roll)]60 = 1 - (5/6)60 = 0.999982 ie 99.9982 per cent

How many rolls of wallpaper in 55 sq meters?
