PROBABILITY PRE-TEST

Probabilities should be written as...

• Unsimplified fractions

• Only simplified fractions

• Percentages only

• Simplified fractions, decimals (exact), or percentages

How many cards in a normal playing deck (excluding Jokers)?

• 48

• 50

• 52

• 54

How many numbers on a standard die?

• 10

• 6

• 4

• 2

In the English alphabet there are 26 letters. How many letters are vowels?

• 5

• 6

• 7

• 8

A sample space in probability is best defined as:

• a list of the different outcomes

• a list of all possible outcomes

• a table

• only a tree diagram

There are two types of probability. They are:

• Experimental and Theoretical

• Fractions and percentages

• Relative frequency and tree diagrams

• Relative frequency and experimental

The sum of the probabilities of all possible outcomes is:

• 0

• between 0 and 1

• between -1 and 1

• 1

Describing the chance of event happening as being likely would mean that the probability would be:

• = 1/2

• = 1

• Between but not equal to 0 and 1/2

• Between but not equal to 1/2 and 1

The probability of an event, E, occurring is:

• Alternate probability

• Supplementary probability

• Complementary probability

• Corresponding probability
