Answer:
a. Kth = 1/n, 1/n-2, 1/n-3,..........
b. Kth= 1/n!
Explanation: This is a mathematics probability and combination problem. It can only be solved using probability and combination rules.
Kth means the number of try she is probably to apply before she can open the door.
For the first problem, heartfilia tries the keys and discard the ones that doesn't open the door. that means for the first time her probability of opening the door is 1/n and for the second time her probability will be 1/n-1 and for the third time it will be 1/n-2, so will her probability of opening the door increases until she gets to the last key which probability will be equal to 1, Therefore the chances she will have to open the door will increase as she tries the key at random,disregarding the ones she has tried before.
The second question involves combination, because she doesn't disregard the ones she has tried before, she may keep trying 1 key many times, since she picks up the key at random. It means that the chance she has to open the door remains the same till she gets the right key. And each try is 1/n! Which means that they is probability of picking up the same key many times, which has reduced her chances of getting the right key.
Answer:
66%; 80%
Explanation:
Hermann Ebbinghaus, a German psychologist pioneered an experiment study on memory where he hypothesize that retention of memory depends on time. On completing particular study, He found that 66 percent of information was lost, while 80 percent of the information was lost after a month. He called this study forgetting curve
<span>hristian apologists such as Henderson (1999) and Birkett (1996) argued that the conflict between Galileo and the Catholic Church is a battle between old science (Ptolemaic astronomy) and new science (Copernican astronomy), rather than a battle between science and religion. Bergman (1996) and Birkett (2000) pointed out that many Catholic clergymen were neutral to Galileo's theory and several Jesuit astronomers even endorsed Galileo's telescopic discoveries when he traveled to Rome in 1611. However, secular scientists who disagreed with Galileo and failed to defeat him took the dispute to the church. It is unfortunate that the Catholic Church was "used" by Galileo's enemies and since then the Christian religion has been misperceived as "an enemy of science." Clausen (2000) and Snow (1999) went even further to assert that not only does the Christian religion not hinder science from development, but also fundamental doctrines of Christian theology help the birth of modern science.</span>
