Ответ:
Option D) 0.65
Step-by-step explanation:
We are given the following in the question:
Percentage of executives who read Time magazine = 35%
Percentage of executives who read U.S. News & World Report = 40%
Percentage of executives who read both Time magazine and U.S. News & World Report = 10%
We have to find the probability that a particular top executive reads either Time or U.S. News & World Report regularly.
Thus, we have to evaluate,
Putting values, we get,
0.65 is the probability that a particular top executive reads either Time or U.S. News & World Report regularly.
Thus, the correct answer is
