Hello.
This question is really puzzling me.
The 3 events E1, E2 and E3 are defined in the same sample space and . P(E1uE2uE3)=1. The events E1 and E2 are independant. Given P(E1)=2/3. P(E2)=1/4 and P(E3)=1/4
Find:
a) P(E1uE2)
b) P(E2uE3)
I've looked through my book for the rules on independant events but cannot seem to find it. The answers are in the back of the book, a) 3/4 b) 1/2. How do I go about doing these?
Thanks
