C784 MODULE 7.11 CONDITIONAL PROBABILITY With Correct Solutions Latest Update CONDITIONAL PROBABILITY RULE dependent events - Answer -P(B[A) = P(A and B)/P(A) P(B[A) -means the probability of B given A A=it rained yesterday B= I water my garden on a certain day p(b) = 0.5, water garden qoday P(B[A)= 0.1 (water garden day after it rains. don't water my garden as often when it rains) suppose we did not know the P(B[A). We record the weather for 100 days and our watering to get an experimental probability. 9/100 days it rained the day before, but we still water the garden. 24/100 days it rained. A= it rains B= water garden P(A)=prob. it rains =24/100 = 0.24
