Question 1197106
.
If A and B are mutually exclusive events with P(A) = 0.75, then P(B)
~~~~~~~~~~~~~



As the problem is worded,  there is  NO  a unique answer.


There are infinitely many possibilities for     P(B).


The only thing that we can state certainly is this inequality


    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0 <= P(B) <= 0.25.



In order for to state that &nbsp;P(B) = 0.25, &nbsp;the problem &nbsp;MUST &nbsp;say in addition that 

A &nbsp;and &nbsp;B &nbsp;are mutually &nbsp;COMPLEMENTARY &nbsp;events - but the problem &nbsp;DOES &nbsp;NOT &nbsp;state it.



Ignore the response by @MathLover1, &nbsp;since it is &nbsp;INCORRECT.
