Denise is trying to open a safe whose combination she does not know. IF the safe has 4000 possible combinations,and she can try 100 different possibilities,what is the probability that she does not pick the one correct combination.
Choose the correct choice from the following options:
A) 1 B) 159/160 C) 0.975 D) 0.775 E) 0
If Denise does not pick the correct combination in first 100 try, then the correct combination is one of remaining 3900. So Probability = 3900/4000 = 0.975.   answer is 0.975.
