PROBABILITY

Back 1

Probability refers to the chance or possibility that
something (such as a particular event or outcome)
will happen or not.

Front 2

CHANCE

Back 2

When a situation is uncertain, chance refers to a
measure or degree of likelihood that a particular
event will occur. Weather forecasters, for example,
report on the chance of rain or snow in the near
future.

AVERAGE

Back 3

The average or mean is the sum of a set of numbers
divided by the total number of items within a set.
With probability, in which there is a degree of
uncertainty, an average can be estimated and used
to make predictions about the future.

BELL-SHAPED CURVE

Back 4

The bell-shaped curve refers to a common
distribution pattern of a data set. Rising in the center,
the curve indicates the average or mean, where most
of the data ranges. At either end, there is a fairly
similar tapering or decrease in data.

ODDS

Back 5

Odds are a way of expressing the likelihood that a
particular event or outcome is favored or will occur
instead of another.

Front 6

SAMPLING

Back 6

A sampling is the act, process or research technique
of selecting a representative portion of a population
in order to gather information about the whole
population. Through sampling, one can learn and
make educated predictions.

CHROMOSOMES

Back 7

Chromosomes are genes inside cells that are passed
from parent to offspring. One chromosome inherited
from the mother and one chromosome inherited
from the father, determines whether an individual is
a boy or girl; either way it is a 1 to 2 probability of
being a boy or a girl.

PREDICTION

Back 8

Prediction is the act of forecasting or foretelling a
future event or outcome based on current
observations, past experiences or reasoning.
Understanding probability assists in making
predictions.

Front 9

THEORETICAL PROBABILITY

Back 9

Theoretical Probability is what should happen in a probability event based on reasoning and calculations.

Front 10

EXPERIMENTAL PROBABILITY

Back 10

Experimental Probability is what does happen in a probability event based on what happens. Ex: If you roll a die six times, you could roll any combination of numbers.
