An urn includes white and black balls. if a random sample of length is chosen, the probability that it consists of exactly white balls: 
Sample area = M + N
we are choosing r balls from the pattern space
So the possibility of having the exactly white ball is ok which means the okay of decided on balls is black
So the probability is
Probability is honestly how probable something is to manifest. each time we are unsure about the final results of an event, we will talk about the probabilities of certain results—how in all likelihood they're. The analysis of activities governed via probability is referred to as information.
Probability is the branch of mathematics concerning numerical descriptions of ways in all likelihood an occasion is to occur, or how in all likelihood it's miles that a proposition is proper. The opportunity of an occasion is more than a few between zero and 1, in which, more or less talking, 0 suggests the impossibility of the occasion and 1 shows reality.
Probability = the number of methods of achieving achievement. the full number of feasible effects. for instance, the possibility of flipping a coin and it being heads is ½, due to the fact there may be 1 manner of getting a head and the whole wide variety of viable consequences is two (a head or tail).

The ways Ancient Roman culture extended and continued throughout the Byzantine Era can be shown with the following examples:
1. "Hagia Sophia ...was an architectural wonder. Like other Byzantine churches, it was crowned by a great dome that symbolized Heaven. Back when the Western Roman Empire was still mighty, it had built many dome buildings."
2. "Like their Western Roman ancestors, the Eastern Romans took great pride in their laws. Over the centuries, however, the laws of the empire had become outdated."
Thus, the Eastern Romans, otherwise, called Byzantine continued the Ancient Roman culture in the construction of architectural wonders and maintenance of Roman laws.

Answer:
b. Jennifer will recall the capitals and their states better than Jeff.
Explanation:
Jennifer and Jeff are studying for their geography exam. Jeff is learning the states' capitals by repeating them over and over. Jennifer is incorporating information she already knows about each state into the name of the capital. While Jeff is repeating "Sacramento is the capital of California, Sacramento is the capital of California," Jennifer is saying "SacraTOMATO is the capital of California" because she knows Sacramento is in the middle of a rich agricultural valley. If the levels-of-processing theory is correct,
Jennifer will recall the capitals and their states better than Jeff.
Jennifer is making use of word and image association in her study based on information she had already acquired, this will enable her to remember what she learnt better than Jeff who is making used of repetition which can only be store in the short term memory and likewise, a confusion in the words can unsettled what he had memorizes
