Book Free Demo1. If \(P(A) = \frac{2}{3}\), \(P(B) = \frac{2}{5}\), \(P(A \cup B) = \frac{1}{3}\), then find \(P(A \cap B)\).
Answer:
\(P(A \cap B) =\)
[Note: Enter numerator and denominator in simplified form.]
2. If \(A\) and \(B\) are two mutually exclusive events of a random experiment and \(P(\text{not} \ A) = 0.45\), \(P(A \cup B) = 0.65\), then find \(P(B)\).
Answer:
\(P(B) =\)
3. The probability that atleast one of \(A\) and \(B\) occur is \(0.6\). If \(A\) and \(B\) occur simultaneously with probability \(0.2\), then find \(P(\overline A) + P(\overline B)\).
Answer:
\(P(\overline A) + P(\overline B) =\)
4. The probability of happening of an event \(A\) is \(0.5\) and that of \(B\) is \(0.3\). If \(A\) and \(B\) are mutually exclusive events, then find the probability that neither \(A\) nor \(B\) happen.
Answer:
\(P(\text{neither} \ A \ \text{not} \ B) =\)
