If  P ( A ) = 0.84,  P ( B ) =0.76 and   P ( A  or  B ) =0.90, then  P ( A  and   B ) is: 3. If  P ( A ) = 0.35,  P ( B ) = 0.45 and   P ( A  and   B ) =0.25, then  P ( A / B ) is: 4. If  P ( A ) = 0.20,  P ( B ) = 0.30 and   P ( and   B ) = 0.06, then   A  and   B  are: 71

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
