In a certain animal population, for each of the first 3 months of life, the probability that an animal will die during that month is 1/10. For a group of 400 newborn members of the population, approximately how many would be expected to survive the first 3 months of life?\nOptions:\n(A) 240\n(B) 246\n(C) 252\n(D) 292\n(E) 298 Stream of consciousness first, then make a decision:
User
Number of newborns that can die in first month = 1/10 * 400 = 40\nSurvived = 360\nNumber of newborns that can die in second month = 1/10 * 360 = 36\nSurvived = 324\nNumber of newborns that can die in third month = 1/10 * 324 = 32\nSurvived = 292
Thus, the answer is (D).
