Does the probability that a continuous random variable take a specific value depend on the probability density function?
No. The probability that a continuous random variable takes a specific value is always zero.
What is the probability the random variable will assume a value between 40 and 60?
It depends on what the random variable is, what its domain is, what its probability distribution function is. The probability that a randomly selected random variable has a value between 40 and 60 is probably quite close to zero.
What happens to the probability of observing a t-random variable between -2 and 2 as you increase the degrees of freedom?
The probability increases.The probability increases.The probability increases.The probability increases.
What is the probability that the random variable has a value less than 5?
That depends on the rules that define the random variable.
What is the probability of five books being placed in alphabetical order of their titles if randomly put on a book shelf?
There are 5! (that is, 120) distinct ways to arrange five items. Only 1 of them will have the books in alphabetical order by title. So the probability that it happens by random is 1/120.
If the probability of getting identical is 0.004 while the probability of fraternal twins is 0.023 then what is the probability that a person chosen at random will not be a twin?
1- P(identical) - P(fraternal) =1-0.004-0.023 =0.973 The probability of being a identical or fraternal twin plus the probability of not being a twin has to add to 1. so 1- probability of being twins=probability of not being a twin ;-)
What is probability that a leap years selected at random will contain 53 Sundays?
probability = 2/7 to be exact, 28/97 (about 28.87%)
What is the fundamental concept for probability and statistics?
The fundamental concept is that there are many processes in the world that contain a random element. If that were not the case, everything would be deterministic and there would be no need for probability of statistics.

How many random variables are needed to plot a probability distribution?
A probability density function can be plotted for a single random variable.
Random sample is a concept of?
Probability.
Does the probability that a continuous random variable take a specific value depend on the probability density function?
No. The probability that a continuous random variable takes a specific value is always zero.
