The area is the sum of 'n' rectangle areas.
The width of the rectangle is size of interval, (domain size)/n
The height of each rectangle is f(interval) as interval moves along domain.
For this example, domain size = 3-1 = 2
size of interval = 2/n
height varies from f(1) to f(3), increasing by 2/n each time.
f(1+(2/n)i)
Putting this together, the area is the sum of:
Since you are given the function f(x). Sub input into f(x) to get area in terms of n and i.
Finally, the summation is:

Answer:
The probability of four girls is:
Step-by-step explanation:
The sample space for 4 children consist of 16 entries and is given by:
{bbbb,bbbg,bbgb,bgbb,gbbb,bbgg,bgbg,ggbb,gbbg,gggg,gggb,ggbg,gbgg,bggg,gbgb,bggb}
i.e. The total number of outcomes=16.
Now the number of outcomes of getting four girls or we can say no boys=1=Number of favourable outcomes {i.e. the outcome is gggg}
Hence,
The probability of getting four girls= (Number of favourable outcomes)/(Total number of outcomes)=1/16
Hence, the probability of four girls is:
