Answer the following question completely with the complete solutions.

Assignment Mode Quiz (Scores displayed when completed) of 100 Question 76 O Events Q and R have probabilities such that: P(Q) 0.8 P(R) 0.4 PeUR) 0.6 PrenR) 0.6 Are events Q and Rindependent? A Yes, because PenR) +AR) Yes, because PeUR PoenR). c. No, because PenR) z Pe POR) D. No, because P(e) POR) z PeUR.

Solution

we say two events Q and R are independent if they satisfy
P(Q^R)=P(Q)*P(R)
plug given values
0.6=0.8*0.4
0.6=0.32
which is clearly not equal
Hence choice C is correct.
