Answer:
Required Probability=
Step-by-step explanation:
We have been given the total 40,000 words
And the words that started with letter T is 6,670
We need to find the probability of the words beginning with T
Words beginning with T will be 
Total words after choosing 20 unique words would be: 


Hence,
Required Probability=

because when you differentiate, only the constant of the x remains (which is m in this case), and c being another constant independent of x, is 0 when differentiated. hence, since dy/dx is the gradient of the line, m is therefore the gradient
