Answer: 0.46

Step-by-step explanation:

We know that when two events X and Y are mutually exclusive, then

[tex]\text{P(X or Y)}=P(X)+P(Y),\ \ \ \text{Since }P(X\cap Y)=0[/tex]

Given:  A and B are mutually exclusive events, with

P(A) = 0.19 and P(B) = 0.2

Now, [tex]\text{P(A or B)=P(A)+P(B)}\\\\\Rightarrow\text{P( A or B)}=0.19+0.27\\\\\Rightarrow\text{P( A or B)}=0.46[/tex]
