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=
0.01x + 0.07y = 0.22
0.03x -0.05y = 0.14
x + 7y = 22
3x - 5y = 14
x = 22 -7y
3*(22-7y) -5y =14
66 - 21y -5y =14
-26y = - 52
y =2
x + 14 = 22
x= 8
