Second Quarterly Examination in Stat&Probab

It is the range of all possible outcomes of an experiment such as rolling dice and tossing coin.

• Sample space

• Probability

• Statistics

• Random variable

A random variable which is finite, distinct or separate value. (countable)

• Discrete

• Finite

• Continuous

• Experiment

It is also called a frequency function which gives you probabilities for discrete random variables.

• Probability Mass Function

• Frequency distribution

• Random equation

• Table/Graph

A random variable which is infinite and pointing any value in interval.

• Continuous

• Finite

• Discrete

• Experiment

After getting all the probabilities of a random experiment, we use the formula to check whether the answers are correct. In using the formula, we just need to get the ______ of all the probabilities and it must be equal to 1.

• sum

• quotient
