Using it's concept, it is found that the range of the function is given by:
all real numbers greater than 0.
<h3>What is the range of a function?</h3>It is the set that contains all possible output values for the function.
In this problem, the function is:
For <u>exponential functions without vertical shifts</u>, as is the case in this problem, the range is given by:
all real numbers greater than 0.

Answer:
34.87% probability that all 5 have a wireless device
Step-by-step explanation:
For each student, there are only two possible outcomes. Either they own a wireless device, or they do not. The probability of a student owning a wireless device is independent from other students. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
81% of students own a wireless device.
This means that
If 5 students are selected at random, what is the probability that all 5 have a wireless device?
This is P(X = 5) when n = 5. So
34.87% probability that all 5 have a wireless device
