Break the numbers under the radical into perfect squares: . Take the perfect squares out: you have two 2's, and 2 x's, on the outside of the radical with 2 and z leftover:
. Multiply everything together to get

Answer:
61.70% probability that he or she will be between 23 and 52 years of age
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X between c and d is given by the following formula.
The numbers of full-time wage and salary workers in each age category are almost uniformly distributed by age, with ages ranging from 18 to 65 years.
This means that . So
(a) what is the probability that he or she will be between 23 and 52 years of age?
61.70% probability that he or she will be between 23 and 52 years of age
