Aand b are mutually exclusive events. p(a) = 0.60 and p(b) = 0.30. what is p(a or b)?

0.90

Step-by-step explanation:    

We have been given that A and B are mutually exclusive events.  

 and          

The formula to find probability of two mutually exclusive events is  

Upon substituting our given values in above formula we will get,

Therefore, the P(A or B) will be 0.90.  

it could be 1,3 and more others to create a cylinder.
