1. What is the difference between an experiment and a trial?
An experiment could be rolling a die 10 times, whereas each of the 10 rolls would be a trial.
2. Can a probability be greater than 1?
No. The highest possible probability is 1.
An event with a probability of 1 is certain to happen.
3. If two events are considered, how do you find the probability of BOTH events happening?
Use the Multiplication Principle and MULTIPLY the probabilities of each event together.
4. What is the difference between RELATIVE FREQUENCY and PROBABILITY.
Relative frequencies are usually obtained from experiments such as throwing a die 100 times, whereas probabilities are calculated from theory.
e.g Knowing that a six-sided die will have a one sixth probability of getting any of the 6 numbers.
