Consider a situation in which P(X) =
and PM) = 1. If P(X and Y) is = , which best describes the events?
They are independent because P(X) · P(Y) = P(X and Y).
They are independent because P(X) + P(Y) = P(X and Y).
They are dependent because P(X). P(Y) = P(X and Y).
They are dependent because P(X) + P(Y) = P(X and Y).

#1-20 state whether the angles are alternate interior, alternate exterior, vertical, or corresponding angles.

Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x

If p(a) = 0.70 and p(b) = 0.20, then a and b are independent events if
