Ok, were starting at when the stock increased first which is 12 cents on monday. to find your answer your going to need to add all of the increased cents first; then subtract.
12 + 14 = 26
So we have 26 cents, now we subtract the 56.
26 - 56 = -30
now we have -30. now we find out how far away on the number line it is from 12. your answer would be 42.
now for your answer, (i did all of that for other people who had the same question but different answer)
your answer would be 112 cents (which is option B)
In this problem, we are given a 10-minute range, from 45 to 55 minutes. The question is asking for a 1-minute range, 50.75 to 51.75 minutes. A 1-minute range out of a total 10-minute range gives us 1/10 chance, or 10% probability.
I would say the answer is b. -8/10
