Simple Probability

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, where 0 indicates impossibility and 1 indicates certainty.

Front

How do you calculate the probability of an event?

Back

The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Front

What is a favorable outcome in probability?

Back

A favorable outcome is an outcome that satisfies the conditions of the event for which the probability is being calculated.

Front

What is the probability of selecting a brown candy from a bowl containing 4 yellow, 6 orange, 3 green, 5 blue, and 2 brown candies?

Back

The probability is 2/20 or 1/10.

Front

How do you find the probability of choosing a letter other than 'A' from the word 'ALGEBRA'?

Back

Count the total letters (7) and the number of 'A's (2). The probability is (7-2)/7 = 5/7.

Front

What is the probability of spinning an even number on a spinner with numbers 1 to 6?

Back

The probability is 3/6 or 50%, since there are three even numbers (2, 4, 6) out of six total numbers.

Front

How do you simplify the probability of landing on 'A' if there are 4 letters in total and 1 is 'A'?

Back

The probability is 1/4, as there is 1 favorable outcome (A) out of 4 total outcomes.

Front

What is the probability of choosing a fruit that is NOT lime from a box containing 3 limes, 5 grapes, and 2 oranges?

Back

The probability is 7/10, since there are 7 fruits that are not limes out of a total of 10 fruits.

Front

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

Back

The total number of outcomes is the sum of all possible outcomes in the experiment.

Front

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

Back

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