To calculate the probability of drawing three sevens in a row from a deck of cards involves the use of the multiplication rule and equals 4/52 + 3/51 + 2/50.
Indicate whether the statement is true or false
For continuous variables which are normally distributed, p(A) equals the area under the curve corresponding to A divided by the total area under the curve.
Indicate whether the statement is true or false
To use probability and inference, data must be discrete.
Indicate whether the statement is true or false
There is no division rule for probability.
Indicate whether the statement is true or false
The multiplication and addition rules can be applied together in the same problem in order to calculate probabilities under some circumstances.
Indicate whether the statement is true or false
The addition and multiplication rules can apply to any number of events.
Indicate whether the statement is true or false
For dependent events, p(A and B) = p(A)p(BA).
Indicate whether the statement is true or false
If A and B are independent then p(BA) = p(A) or p(B).
Indicate whether the statement is true or false
Two events are independent if the occurrence of one has no effect on the probability of occurrence of the other.
Indicate whether the statement is true or false
When two events are mutually exclusive then p(A and B) must equal 1.00.
