Used medication (M) Used placebo (L) Total Condition improved (I) 20 280 300 No change (N) 340 2500 2840 Condition worse (W) 40 2820 2860 Total 400 5600 6000 Assume that a participant is selected at random. Let M be the event that the participant used the medication, L the event that the participant used th placebo, I the event that the participant's condition improved, and so on as shown by the letters in the headings. (a) P(IM)= Check Clear Give the exact answer; not a decimal approximation. (b) P(M|D) = Check Clear Give the exact answer; not a decimal approximation. Check Clear (c) P(I)= Give the exact answer; not a decimal approximation. (d) P(M)= Check Clear Give the exact answer; not a decimal approximation. (e) Test the events I and M for independence. Independent O Dependent Independent independence.
