Simple Probability Independent and Dependent

the outcome of the second event does not depend upon the outcome of the first event

• sample space

• dependent

• independent

• impossible

The measure of the likelihood that an event will occur. The chance that an event will happen. A ratio of chance/all chances.

• odds

• probability

• outcomes

• certain

The probability of an event is written as P(event).

• False

• True

A measurement of the likelihood of an event or events occurring on a scale of 0 to 1 is called - 

• data

• luck

• probability

• trials

The extent to which something is likely to occur is known as - 

• sample space

• an event

• probability

• data

The likelihood that a single, specific event will occur is called - 

• sample space

• compound probability

• a complement

• simple probability

In probability theory, the sum of an event (A) occurring and the same event NOT occurring (not A) is always - 

• 0

• based on the sample space

• variable

• 1

P(A) + P(not A) = 1

• True

• False

Which of the following expressions can be used to calculate the probability of two related events occurring?

• P(event) x 2

• P(event 1) +   P(event 2)

• P(event 1) x     P(event 2)

• P(event 1 + 2)
