Question 1125482: Show me how to break this down please.
29% of adults would pay more for environmentally friendly products. You randomly select 10 adults. Find the probability that the number of adults who would pay more for environmentally friendly products is (a) exactly two, (b) more than two, and (c) between two and five, inclusive.
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! exactly two means 10C2, the number of ways to choose 2, *.29^2*.71^8=0.2444
more than 2 is 1-0,1,2
probability of 0 is .71^10=0.0326
probability of 1 is 10*.29*.71^9=0.1330
probability of the 3 is 0.4100
probability of everything else, the answer, is 0.5900
between 2 and 5:
probability of 2 is 0.2444
of 3 is 10C3*0,29^3*0.71^7=0.2662
of 4 is 0.1903
of 5 is 0.0933
total is 0.7942
