I get: P(geo and math) = P(geo) + P(math) - P(geo or math)

= 0.65 + 0.60 - 0.77

= 1.25 - 0.77

= 0.48

**PsyDAG**, Sunday, February 13, 2011 at 10:29amYou need to make up your mind. Is the .77 for both or either-or?

I would assume that the above data (.77) is not needed.

To find the probability of both/all events occurring you need to multiply the probability of the individual events.

.65 * .60 = .39
