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

What is the probability of flipping heads on the coin?

The probability of flipping Heads on a coin is 1 - a certainty - if the coin is flipped often enough. On a single toss of a fair coin the probability is 1/2.


What is the probability of a coin landing on heads twice when it is flipped 2 times?

25%


If you flipped two coins what is the probability that the first coin is heads?

The probability is always 50/50 even if you flipped 100 or 1000000 coins.


If a coin is flipped twice what is the probability that both will be heads?

The sample space is HH, HT, TH, HH. Since the HH combination can occur once out of four times, the probability that if a coin is flipped twice the probability that both will be heads is 1/4 or 0.25.


A fair coin is flipped three times what is the probability that the coin lands heads each time?

7/8


In a probability experiment Eric flipped a coin 36 times. The coin landed on heads 24 times. What is the ratio of heads to tails in this experiment?

2 to 1


What is the probability that a coin flipped four consecutive times will always land on heads?

The probability that a coin flipped four consecutive times will always land on heads is 1 in 16. Since the events are sequentially unrelated, take the probability of heads in 1 try, 0.5, and raise that to the power of 4... 1 in 24 = 1 in 16


What is the probability of getting heads at least once if a fair coin is flipped three times?

7/8


A coin is flipped 2 times and the number of heads is observed. Find the probability of tossing 2 heads or 2 tails.?

It is 1/2.


A coin is flipped eight times What is the probability that the outcome will NOT be eight heads?

Probability of not 8 heads = 1- Prob of 8 heads. Prob of 8 heads = 0.5^8 = 0.003906 Prob of not 8 heads= 1- 0.003906 = 0.99604


What are the possible outcomes of a coin that is flipped?

The possible outcomes of a coin that is flipped are heads or tails.


What is the probability of winning by getting more heads when flipping a coin once or flipping a coin twice?

Your question is a bit difficult to understand. I will rephrase it as follows: What is the probability of getting a head if a coin is flipped once? p = 0.5 What is the probability of getting 2 heads if a coin is flipped twice = The possible events are HT, TH, HH, TT amd all are equally likely. So the probability of HH is 0.25. What is the probability of getting at least on head if the coin is flipped twice. Of the possible events listed above, HT, TH and HH would satisfy the condition of one or more heads, so the probability is 3 x 0.25 = 0.75 or 3/4. Also, since the probability of TT is 0.25, and the probability of all events must sum to 1, then we calculate the probability of one or more heads to be 1-0.25 = 0.75
