Suppose you are taking an accounting course and a writing course next semester. You like accounting so you believe that probability af getting an A in accounting is 0.75. On the other hand, writing is not as interesting to you so the probability of getting an A in that class is 0.50. It will be challenging to manage both courses at the same time so the probability of getting an A in both classes is about 0.25. Are the events A in accounting and A in writing independent?
- No b/c 0.75*0.50 does not = 0.25
- Yes b/c 0.75*0.50 does not = 1.00
- Yes b/c 0.745*0.25 does not = 0.25
- No b/c 0.75+0.50 does not = 1.00
