A die is thrown. If A is the event 'the number appearing is a multiple of 3 and B is the event 'the number appearing is even', then A and B are : |
dependent events independent events $P(A \cap B)=\frac{1}{3}$ $P(B)=\frac{1}{3}$ |
independent events |
A and B are independent events as outcome of one doesn't depend upon other $P(A) = \frac{2}{6}$ [as 3 and 6 are only multiples of 3 ⇒ P(A) = $\frac{1}{3}$ P(B) = $\frac{3}{6}$ [2, 4, 6 are three even outcomes P(B) = $\frac{1}{3}$ P(A ∩ B) = $\frac{1}{6}$ (6 is only even multiple of3) |
