Explanation / Answer

61.

A)total number of Hr professional=592

No.of hr professional from established economy=249

So probability that a randomly selected hr professional is from established economy=249/592 =0.4206

B) number of peoples from established economy=249

Number of peoples agree to statement=252

Number of peoples from established economy and agree to statement =122

So no.of peoples from established economy or agree to statement =n(A)+n(B)-n(A and B)=249+252-122=379

So required probability=379/592=0.6402

C) number of peoples not agree with statement "HR as strategic function" and from emerging economy=121

Required probability=121/592=0.2044

D) number of peoples from emerging economy=343

Number of peoples not agree with statement"hr as strategic function"=199

Number of peoples not agree with statement and from emerging economy=121

So number of peoples not agree with statement and from wmemergi economy=n(A)+n(B)+n(A and B)=343+199-121=421

So required probability=421÷592=0.7111
