Short Quiz - Chapter 13 Class 12 Probability

If E and F are two events such that \(\mathrm{P}(\mathrm{E})>0\) and \(\mathrm{P}(\mathrm{F}) \neq 1\), then \(\mathrm{P}(\overline{\mathrm{E}} / \overline{\mathrm{F}})\) is

The probability distribution of a random variable X is given by :



Then \(\mathrm{E}(\mathrm{X})\) of distribution is

Let E and F be two events such that \(\mathrm{P}(\mathrm{E})=0 \cdot 1, \mathrm{P}(\mathrm{F})=0 \cdot 3, \mathrm{P}(\mathrm{E} \cup \mathrm{F})=0 \cdot 4\), then \(P(F \mid E)\) is :

Let A and B be two events such that P(A)=0.4, P(A \(\cup\) B)=0.7 and P(B) = p. For what choice of p are A and B independent ?
