Answer: The value of P(A or B) =0.60
Step-by-step explanation:
Given: A and B are two events.
P(A)=0.25 , P(B)=0.5 and P(A and B)=0.15
We know that the value of P(A or B) is given by the formula :
[tex]\text{P(A\ or\ B)}=\text{P(A)+P(B)}-\text{P(A\ and\ B)}\\\\\Rightarrow\ \text{P(A\ or\ B)}=0.25+0.5-0.15\\\\\Rightarrow\ \text{P(A\ or\ B)}=0.60[/tex]
Hence, the value of P(A or B) =0.60
