DPISD Probability (Experimental and Theoretical)


Terms in this set (...)

compound event
An event made up of two or more simple events.
In probability, any activity based on chance (such as tossing a coin, spinning a spinner, picking a card)
experimental probability
The ratio (fractions) of the number of times an event occurs to the total number of trials, or times that the activity is performed.
A possible result of a probability experiment. {1, 2, 3, 4, 5, 6, 7, 8}
A number from 0 and 1 (or 0% to 100%) that describes how likely an event is to occur.
simple event
An event consisting of only one outcome.
Each repetition or observation of an experiment. (Example: We say there are n= 10 trials if we are flipping a coin 10 times in the experiment)
theoretical probability
The ratio (fraction) of the number of ways an event can occur to the number of equally likely outcomes.
An outcome or set of outcomes of an experiment or situation
favorable outcome
The outcome you are hoping to observe.
independent events
An experiment with two outcomes which are not related. Flipping a coin and rolling a die. Picking a ball from a bag, putting it back, and picking a new one.
dependent events
An experiment with two outcomes which are related. Picking two balls from a bag, without replacement.
Sample Space
The set of all possible outcomes
