Participants in a study of a new medication received either medication a or a placebo. find p(placebo and improvement). of all those who participated in the study, 80% received medication a. of those who received medication a, 76% reported an improvement. of those who received a placebo, 62% reported no , i have absolutely no clue how to go about this. maybe walk me through it? i don't just want the answer, .

7.6%

Step-by-step explanation:

What we know: 80% received medication A - well if 80% received the medication then that must mean that 20% did not recieve medication A, because we know 100% - 80% = 20%

Of those who received the placebo, 62% reported no improvement- well if 62% showed no improvement on the placebo that must mean that 38% DID show improvement on the placebo because we know that 100% - 62% = 38%

To find P (placebo and improvement) we multiply these two percentages- those who received a placebo, and those who showed improvement on the placebo. So 20% becomes 0.20 and 38% becomes 0.38. 0.20 x 0.38 = 0.076

Now we can convert this into a percentage! :) move the decimal over two places to the right and we get 7.6%
