The probability of getting a number greater than $2$ in throwing a die is
$\frac{1}{3}$
$\frac{2}{3}$
$\frac{1}{2}$
$\frac{1}{6}$
(b) Required probability $ = \frac{4}{6} = \frac{2}{3}.$
On her vacations Veena visits four cities $(A,\,B ,\, C$ and $D$ ) in a random order. What is the probability that she visits $A$ either first or second?
Two dices are rolled. If both dices have six faces numbered $1,2,3,5,7$ and $11,$ then the probability that the sum of the numbers on the top faces is less than or equal to $8$ is
Three fair coins are tossed. If both heads and tails appears, then the probability that exactly one head appears, is
If $P(A) = 0.65,\,\,P(B) = 0.15,$ then $P(\bar A) + P(\bar B) = $
Three persons work independently on a problem. If the respective probabilities that they will solve it are $\frac{{1}}{{3}} , \frac{{1}}{{4}}$ and $\frac{{1}}{{5}}$, then the probability that none can solve it
