To find : The number of ways a computer can randomly generate one or more such integers from 1 through 30. Two distinct integers whose sum is 27.
Solution :
We have given the numbers from 1,2,3,4......,29,30.
In order to get two distinct numbers having the sum 27,
There are the possibilities :
1+26=27
2+25=27
3+24=27
......
24+3=27
25+2=27
26+1=27
The maximum number taken is 26.
So, There are 26 possible way to determine two distinct integers whose sum is 27.
