Question 1048998: I'm not really following this question and could use your guidance:
A and B are two disjoint events. If P(A) = 0.3, and P(B) = 0.4, then P(A AND B) is
(a) 0.7
(b) 0.12
(c) 0
(d) cannot be determined
I feel like this is suspiciously straightforward, wouldn't it be "a" .7?

You can put this solution on YOUR website! A and B are two disjoint events. If P(A) = 0.3, and P(B) = 0.4, then P(A AND B) is
(a) 0.7
(b) 0.12
(c) 0
(d) cannot be determined
I feel like this is suspiciously straightforward, wouldn't it be "a" .7?
=================
It's the product, = 0.12.
Both events must occur, that's less likely than just one out of 2.
----------
P(A OR B) is the sum, 0.7
