Holiday Theoretical Probability 1

Front

What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

How do you calculate the probability of an event?

Back

Probability of an event = (Number of favorable outcomes) / (Total number of possible outcomes).

Front

What is a favorable outcome in probability?

Back

A favorable outcome is the specific result of an event that we are interested in.

Front

What is the total number of outcomes in a probability experiment?

Back

The total number of outcomes is the complete set of all possible results of an experiment.

Front

If there are 16 guests at a party, how do you find the probability of selecting someone wearing a snowman sweater?

Back

Count the number of guests wearing snowman sweaters (5) and divide by the total number of guests (16): 5/16.

Front

What is the probability of randomly picking a silver gift box from 28 boxes?

Back

There are 4 silver boxes, so the probability is 4/28, which simplifies to 1/7.

Front

How do you find the probability of selecting a gingerbread cookie from a tray of 15 cookies?

Back

Count the number of gingerbread cookies (4) and divide by the total number of cookies (15): 4/15.

Front

What is the probability of selecting a peppermint candle from 24 candles?

Back

There are 6 peppermint candles, so the probability is 6/24, which simplifies to 1/4.

Front

How do you calculate the probability of selecting a gold ornament from 12 ornaments?

Back

Count the number of gold ornaments (3) and divide by the total number of ornaments (12): 3/12, which simplifies to 1/4.

Front

What does it mean if the probability of an event is 0?

Back

If the probability is 0, it means the event cannot occur.
