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 1/6. For a group of 200 newborn members of the population, approximately how many would be expected to survive the first 3 months of life? Choose the correct option
A) 116
B) 146
C) 152
D) 162
E) 170
The probability of survival for each of the first 3 months of life is 1-1/6= 5/6, so of 200 newborn 200*5/6*5/6*5/6=~116 is expected to survive.   116nswer: 116.
