How do you find binomial probabilities using a binomial table?
Read the instructions that accompany the table: they do not all have exactly the same layout.
What is the probability that a die will land ona certain number?
There are six sides to a die. If we assume that all sides have the same chance of coming up then each side has a probability of 1 in 6 or 1/6. This is the theoretical probability. Of course if the die is not perfectly shaped and weighted then it will not be 'fair' and the sides will have different probabilities of coming up.
How do you obtain a probability distribution?
Find all the possible outcomes and the probabilities associated with each.

What is the sum of the probabilities of all the outcomes in a sample space?
1.
What area under a normal curve adds up to?
The area under any probability density function including the normal distribution must equal 1, as the sum of the probabilities of all outcomes must equal 1. However, as the domain of outcomes goes from minus infinity to positive infinity, this fact is a theoretical one, and any practical problem will have cumulative probabilities less than 1.
