1. We assume, that the number 40 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 40, so we can write it down as 100%=40.
4. We know, that x% equals 21 of the output value, so we can write it down as x%=21.
5. Now we have two simple equations:
1) 100%=40
2) x%=21
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=40/21
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 21 is what percent of 40
100%/x%=40/21
(100/x)*x=(40/21)*x - we multiply both sides of the equation by x
100=1.90476190476*x - we divide both sides of the equation by (1.90476190476) to get x
100/1.90476190476=x
52.5=x
x=52.5
now we have:
21 is 52.5% of 40

Answer:
The probability that two have ever boycotted goods for ethical reasons.= .2789
Step-by-step explanation:
Given - The survey found that 23% of the respondents have boycotted goods for ethical reasons .
The probability of success ( p) = 23 = 0.23
The probability of failure ( q) = 1 - p = .77
n = 6
Let X be the number of British citizens boycotted goods for ethical reasons.
The probability that two have ever boycotted goods for ethical reasons.
( Using Binomial distribution )
