In the case above, Talib work is not correct as one need to first switch x and y before one can solve for y.
<h3>What is the variables about?</h3>Note that:
y=-8x+4
y-4=-8x
(y-4)/-8=x
Since the independent variable x is known, one can switch the variable labels and thus it will be:
y=(x-4)/-8
f^-1(x)=(x-4)/-8
This can be written again as:
f^-1(x)=(4-x)/8 :P
Thus one can say No, as he forgot to switch the variable labels after solving for the independent variable.
In the case above, Talib work is not correct as one need to first switch x and y before one can solve for y.

Answer:
0.344 = 34.4% probability that at least 1 of them have blue eyes.
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they have blue eyes, or they have not. The probability of a person having blue eyes is independent of any other person. 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.
A survey reports that the probability a person has blue eyes is 0.10.
This means that
4 people are randomly selected at Miramar College
This means that
Find the probability that at least 1 of them have blue eyes.
Either none of them have blue eyes, or at least one do. The sum of the probabilities of these events is decimal 1. So
We want . So
In which
0.344 = 34.4% probability that at least 1 of them have blue eyes.
