The probability of getting a C in stat is .20. if students attend class regularly, the probability of getting a C is .05. are attending class regularly and getting a C in stat independent events? show why

Solution

No. Independent events don\'t affect each other\'s probabilities.

As you can see here, P(C|NOT ATTEND) = 0.20 without attending.

When you attended, it CHANGED to 0.05.

Thus, they are not independent events.
