I've got a question here asking me to explain why events A and B cannot be mutually exclusive events.(adsbygoogle = window.adsbygoogle || []).push({});

P(A)=0.75

P(B)=0.65

And then to comment about P(AuB) and P(AuB)

I've started of by assuming that they are mutually exclusive

and used the addition formula

P(AuB) = P(A) + P(B)

to get an answer greater than 1 therefore cannot be probability function

but I haven't exactly proved that the events A and B are not mutually exclusive events.

Could someone please point me to the right direction.

Thanks in advance
