Answer:
B.
Step-by-step explanation:
The sample size taken for the school is too small.
5 people not being vegetarian does not mean NO OTHER students are vegetarian also. Thus, an assumption based on this probability of 5 people would not be correct unless fully supported. This makes option A wrong.
Answer B is correct because with small numbers, probability varies a lot and may change drastically with the addition of data.
For example: the 6th person we sample says he/she is a vegetarian.
This would change the probability drastically to 1/6 = 0.1667
Because this is a drastic change, and fluctuation is clear, answer B is correct.
C is wrong because probability is not subjective.
Answer:
The total change in his account is of -$85, that is, a loss of $85
Step-by-step explanation:
We combine these changes. So
On Tuesday, he withdrew $90 from his account, which means that, the total change, initially of $0, is now of -$90.
On Thusday, he deposited $20, which means that the total change of -$90 is now of -$90 + $20 = -$70
On Friday, he wrote a check of $15, removing 15 from his account, which means the total change will be of -$70 -$15 = -$85
