The table shows the results of a research study that investigated the therapeutic value of
vitamin C in preventing colds. A random sample of 300 adults received either a vitamin C pill or
a sugar pill each day during a 2-week period, and the adults reported whether they contracted a
cold during that time period. What is the probability of adults who received a sugar pill reported
contracting a cold? |

Vitamin C __ 21 ______ 129 _____ 150

Sugar Pill __ 33 _______117 _____ 140

Total ______54 ______ 246 ____ 300

Required outcome = cold adult reported = 33

Total possible outcome = total sample = 300

33 / 300 = 0.11
