Question

A. Sue calculated the probability the both teams reach the top in the following manner: P(team A reaches the top and Team B reaches the top)=(.70)(.85)=0.595

In finding the probability, Sue assumed that the two events are:
i. Independant ii Dependant iii Mutually exclusiveiv Not Mutually Exclusive

B. assuming that Sue was correct in part a, what is the probability that Team A OR team B reaches the top?

Answer 1

b.) .955
