Answer:

Probability Distributions

A listing of all the values the random variable can assume with their corresponding probabilities make a probability distribution.

A note about random variables. A random variable does not mean that the values can be anything (a random number). Random variables have a well defined set of outcomes and well defined probabilities for the occurrence of each outcome. The random refers to the fact that the outcomes happen by chance -- that is, you don't know which outcome will occur next.

a school wants to build a rectangular playground that will have a diaonal length of 75 yards. how wide can the playground be if

adoni [48]

You would use the Pythagorean Theorem.
a2 + b2 = c2
302 + x2 = 752
900 + x2 = 5625
900 – 900 + x2 = 5625
X2 = 5625
√(x^2 ) = √5625
X = 75
It is 75 yards wide. I've included a drawing of the rectangle if it helps.
