If P(E)\mathrm{P}(\mathrm{E}) denotes the probability of an event EE, then EE is called certain event if :

Options

  1. AP(E)=0\mathrm{P}(\mathrm{E})=0
  2. BP(E)=1P(E)=1
  3. CP(E)\mathrm{P}(\mathrm{E}) is either 0 or 1
  4. DP(E)=1/2P(E)=1 / 2

Correct answer

B. P(E)=1P(E)=1

Step-by-step solution

If P(E)=1P(E)=1 then EE is called certain event.
