**1. What is the difference between an experiment and a trial?**

An

experimentcould be rolling a die 10 times, whereas each of the 10 rolls would be atrial.

**2. Can a probability be greater than 1?**

No. The highest possible probability is 1.

An event with a probability of 1 is

certainto 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 frequenciesare usually obtained from experiments such as throwing a die 100 times, whereasprobabilitiesare calculated from theory.e.g Knowing that a six-sided die will have a one sixth probability of getting any of the 6 numbers.
