W.k.t, \[A\cup B\] denotes that atleast one of the events occurs and \[A\cap B\] denotes that two events occur simultaneously.
Therefore, the required answer is \[1.1\].
The probability that at least one of the two events A and B occurs is \[0.6\]. If A and B occur simultaneously with probability \[0.3\], evaluate \[P(\overline{A})+P(\overline{B})\]
