From the word `$POSSESSIVE$', a letter is chosen at random. The probability of it to be $S$ is
$\frac{3}{{10}}$
$\frac{4}{{10}}$
$\frac{3}{6}$
$\frac{4}{6}$
A die has two faces each with number $^{\prime}1^{\prime}$ , three faces each with number $^{\prime}2^{\prime}$ and one face with number $^{\prime}3^{\prime}$. If die is rolled once, determine $P(1$ or $3)$
A coin is tossed until a head appears or until the coin has been tossed five times. If a head does not occur on the first two tosses, then the probability that the coin will be tossed $5$ times is
Two card are drawn successively with replacement from a pack of $52$ cards. The probability of drawing two aces is
In a class of $60$ students, $40$ opted for $NCC,\,30$ opted for $NSS$ and $20$ opted for both $NCC$ and $NSS.$ If one of these students is selected at random, then the probability that the student selected has opted neither for $NCC$ nor for $NSS$ is
A card is selected from a pack of $52$ cards. Calculate the probability that the card is black card.
