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

The probability is 1.

The probability is 1 as all values on a die are less than 7.

Assuming that the faces of the 20 sided die are numbered 1 to 20, then the probability of rolling a number less than 9 is 8 in 20, or 0.4.

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.

The probability of rolling a number less than 1 on a standard 6-sided die is zero. It will not happen.

Assuming that the faces of the 20 sided die are numbered 1 to 20, then the probability of rolling a number less than 9 is 8 in 20, or 0.4.

There are six possible outcomes of rolling a six sided die.However, only two of these (1 and 2) are favorable.So, the probability of rolling less than three is 2/6 = 1/3.

There are twenty six ways out of thirty six possible rolls of two dice to hit a number less than nine OR a seventy two percent probability.

Assuming it is a regular 6 sided die, it would be 4/6 or 2/3.
