How many migration waves were believed to have populated North America prior to European contact?

The number of possible outcomes of tossing a coin 7 times.

A sample space consists of six simple events, S = {E1, E2, E3, E4, E5, E6}. If P(E1) = 0.10, P(E2) = 0.14, P(E3) = 0.4, P(E4) = 0.20, P(E5) = 0.10, and P(E6) = 0.06. Are events B and C independent?

An oil company purchased an option on land in Alaska. Preliminary geologic studies assigned the following prior probabilities.                                                                                                                                                   After 200 feet of drilling on the first well, a soil test is taken. The probabilities of finding the soil identified by the test follow.  [ P (Medium-quality oil / soil) = ………………………….. Note: use Bay’s theorem in this part.
