**PsyDAG**, Monday, March 4, 2013 at 1:03pmIf the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.

2 correct = .2^2 * .8^4 = ?

1 correct = .2 * .8^5 = ?

3 correct = .2^3 * .8^3 = ?

4 correct = .2^4 * .8^2 = ?

Either-or probabilities are found by adding the individual probabilities, so add the probabilities you have found.
