Probability
The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

What is the event space for rolling a number greater than 2 with one die?
The inequality with the terms 2x, 3 and 7 can be written as 2x -3 = 7, 2x + 3 = 7, 2x * 3 = 7, and 2x/3 = 7. This means that the solutions are 5, 2, 7/4, and 21/2 respectively.
Why is a two-tailed test preferred over a one-tailed test?
In general, it is not. A one-tailed test is more powerful but it does require the alternative hypothesis to be one sided and, in therefore requires some expectation about the observations if the null hypothesis is not true.
The question, therefore, is appropriate only when the experimenter has extremely limited information about the experiment - not a very common occurrence.

What is the theoretical probability of rolling a even number on a die?
There are 6 sides to a di. Each side has an equal number of odd or even numbers. The chances are 50/50 that you could roll an even number with one di. Using two, the mathematical possibilities are unknown to me. But I would say it would change the odds by hundreds.
Spade: 1 in 4
Ace: 1 in 13
What is the probability that type 1 error will be made z -2.575 or z 2.575?
The probability is 0.005012, approx.
What is the probability that the spinner stop in multiple of 3. The spinner is numbered 1 through 8?
Total number of possible stops = 8
Number of successful stops = 2 (stops on 3 or on 6 are successful)
Probability = 2/8 = 25%
How companies use probability?
Companies use probability in many different ways. For example, they may use it for quality control, or for risk analysis.
What is the relationship between the probability of a simple event and its complement?
If the probability of an event is p, then the complementary probability is 1-p.
For a die it is 1/3. For anything else (a spinner, for example), there is not enough information.

When two dice are rolled find the probability of getting a sum less than 10?
There are 36 combinations of two dice. each have 1 to 6
To get 10 or more requires 4 +6, 5 +5, 5 +6 , 6+5, 6 +4, or 6+6, which are 6 combinations, leaving 36-6 = 30 combinations of less than 10
30/36 = 5/6 probability of getting sum less than 10
What is the probability that z is greater than .5?
Pr(Z > 0.5) = 0.3085 (approx).
Pr(Z > 0.5) = 0.3085 (approx).
Pr(Z > 0.5) = 0.3085 (approx).
Pr(Z > 0.5) = 0.3085 (approx).
What is the probability that a randomly selected person will be both over 50 and female?
The answer depends on the demography of the population from which the person is randomly selected.

What is the probability of numbers 5 and above?
The answer depends on what the experiment is and since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.

Assuming that you are using a full deck of playing cards, excluding Jokers, there would be four 3s in a deck of fifty-two total cards, making your chances of drawing a 3 the first time 1:13. However, to draw two 3s in a row in a true random scenario, we start with the condition that you have already drawn your first 3 (the 1:13 chance). Going from here, we would then have another 1:13 chance of drawing a 3, so we simply multiply the two ratios to arrive at a probably of 1:169.
yes. the probability of winning the dollar increases from 1\3to 2\3 by switching.
