If two events have nothing in common so they can’t occur simultaneuosly

Ways something can be done=

If you can do a task in n1 number of ways and a second task in n2 number of ways, then both tasks can be done in n1 x n2 number of ways.

The sum of all probabilities must be equal to _.

Probability is based on observation, not theorizing.

P(A ____ B)=P(A) + P(B) _______ rule and for ______events only

Probability must add up to ____

Two events A and B are independent if knowing that one occurs doesn’t change the chance the other will occur then you multiply the two to figure out the probability.

In a and b

Graph that shows if events are disjoint or intersecting.

Probability has to be greater or equal to ___ and less than ____

If A and B are independent then their complements are ______

P(A) = (count of outcomes in a) / (count of outcomes in s) = (count of outcomes in A) / k.

The probability that an event doesn’t occur is _____ the probability the event does occur.

If two events have no outcomes in common, the probability that one or the other occurs is the ___ of their individual probability.

If something has two sides to something it _______ mean there is a 50% probability of it happening.

Probability is empirical. T/f

P(A _ B) = P(A) x P(B). ________rule

P(A^C) = 1 - P(A) is the _____ rule

Begins with a point and draws a line to each possible outcome.

When you put the cards back into the deck

hint

Answer

An event with no outcomes. Uses the sign Ø.

Probability event doesn’t occur= (answer in words

When you leave the cards out of the deck.

set of all possible outcomes

Chance behavior is _______ in the short run but has a _______ pattern in the long run.

Probability is ____ term frequency.

Any outcome of a phenomenon where the proportion of times the outcome would occur with a lot of repitions.

Has outcomes that can’t be predicted but nonetheless has a regular distribution in many repititions.

In a or b

any outcome or set of outcomes of a random phenomenon, subset of the sample space.

When one outcome doesn’t affect the next outcome.

mathematical description of a random phenomenon consisting of two parts: a sample space (S) and a way of assigning probabilities to events.

Any probability is between ___and____

When individual outcomes are uncertain but there is a regular distribution over a large amount of outcomes.

Probability the event doesn’t occur

Consists of sample space S and an assignment of probabilities.

Multiplication rule only applies to ________ events

Probability that one or the other of two events will occur because they’re disjoint.
