It means you have 100% chance or certain.
A probability of one means that the outcome will definitely occur.Not asked, but answered for completeness sake - a probability of zero means that the outcome will definitely not occur. Probability always lies between zero and one, inclusive.
If the probability of a event is zero, then the event cannot occur. Therefore, if the probability of an even number is zero, then the probability of an odd number is one.
The answer depends on what you mean by "do". Does it mean calculate individually, calculate the probability of either one or the other (or both), calculate the probability of both, calculate some function of both (for example the sum of two dice being rolled)?
It is a probability distribution in which the probability of the random variable being in any interval on one side of the mean (expected value) is the same as for the equivalent interval on the other side of the mean.

The probability level for an outcome is the probability that the outcome was at least as extreme as the one that was observed.
It is spinner such that the probability that it comes to rest on any one edge is the same as the probability for any other edges.
From a probability perspective fair means equal probability.
It means multiply, Probaility of A and B means probability of A multiplied by probability of B.
The mean of a binomial probability distribution can be determined by multiplying the sample size times the probability of success.
Given the way you have worded the question I take it to mean, what is the probability of drawing at least one spade?We can do this most easily by asking first, what is the probability of drawing no spades on each of the 80 times. This is 39/52. The probability of doing this 80 times is (39/52)80.Then the probability of not doing this is 1 - (39/52)80, which is quite close to one. The probability of drawing at least one spade is almost one.
The significance of the mean of a probability distribution is that it is the most probably thing to happen. The mean is the average of a set of values. If it is the average of a probability distribution, it is the most probable part.
One is the probability, or certain to occur.
Likely means the same as probable and probable refers to the probability that something might happen, Probability is measured using a scale of probability from zero to one. Zero means that the event will definitely not happen whereas a probability of 1 means that the event is certain to happen, Similarly a probability of 0.5 means that the event is just as likely not to happen as to happen. What is the probability that you could swim the Atlantic unaided? Zero What is the probability that a bird will die? One What is the probability that I can throw a 1 with a dice? 1 out of 6 = 0.1666666....... What is the probability that I can toss a "heads" with a coin? 50% = 0.5 = one half
I suppose you mean, at least one of those numbers. Just calculate the probability of NOT getting any of those, and take the complement. The probability of not getting a one nor a five on a single die is 4/6 or 2/3. For two dice, the probability is 2/3 x 2/3 = 4/9. So, the probability of getting at least a one or a five with two dice is 1 - 4/9 = 5/9.I suppose you mean, at least one of those numbers.

If you mean 43%, then the probability that it will not snow is 57%, 0.57 or 57/100.
The mean of a discrete probability distribution is also called the Expected Value.
