There are actually 1024 bytes in a kilobyte. Many people think there are exactly 1000 in conformance with the SI standard, but the number 1000 does not often come up in computers. 210, however, does since a computer thinks in binary instead of deciaml, and since that is approximately 1000, 210 or 1024 bytes comprise the kilobyte. Similiarly, there are 1024 kilobytes in a megabyte.

Question: If you flip a coin twice, what is the probability that it will land on heads either the first or second time?

The probability of the and of two thing happening is the product of the liklihood of each of them occuring. The questoin posed here is an or, however. But if you understood the logic to the last question, then you know how to convert an or to an and. Since the chances of a coin landing on heads (and not landing on heads) is 1/2, the question can be writen as: 1/2 or 1/2 not (1/2 and 1/2) not (1/4) 3/4
