A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

It is approx 0.99989, that is, a near certainty.


I rolled the dice 120 times what's the probability of getting a 6?

If you rolled a die 120 times, the probability of getting a 6 is one in six. It does not matter how many times you roll the die - the probability is still one in six - except that the long term mean will approach the theoretical value of 0.166... as the number of trials increases.

How do you work out the probability that a biased dice will land on a six is 0.35?

You roll it many times. The probability that it lands on a six is the number of times that it lands on a six divided by the number of times the die has been rolled.


If a fair die is rooled 5 times what is the probability of getting six 6's?

Since the die is rolled (or even rooled) only 5 times, the answer is that the probability is 0.


A number cube is rolled 2 times in a row What is the probability of rolling a 3 both times?

When a number cube is rolled twice, there are 36 possible outcomes. (1,1),(1,2),....(6,6). (3,3) occurs only once. Therefore, the probability of rolling a 3 both times is 1/36.

If a die is rolled 3 times what is probability getting 4 threes?

there is 0% probability, unless you are some super nerd, and calculate the chance of it splitting the six and you getting two threes in one roll :p


A fair die is rolled 9 times compute the probability that a one appears exactly once?

The probability of a one being rolled in a fair die is 1 in 6, or 0.1666... . The probability of a one not being rolled is 5 in 6, or 0.8333... . The probability, then, of exactly one one being rolled in nine rolls is 1 in 6 times 5 in 6 to the 8th power, or about 0.0388.


What is the probability of rolling the same number when three number cubes are rolled?

The first roll doesn't matter for probability, it just sets the number to be rolled by the other two. So: P(rolling the same number three times) = P(rolling a particular number)2 = (1/6)2 = 1/36
