Consider the experiment of rolling a die. Let $A$ be the event 'getting a prime number ', $B$ be the event 'getting an odd number '. Write the sets representing the events $^{\prime}$ not $A\,^{\prime}$.
Here $S =\{1,2,3,4,5,6\}$, $A =\{2,3,5\}$ and $B =\{1,3,5\}$ Obviously
$^{\prime}$ not $A^{\prime}=A^{\prime}=\{1,4,6\}$
From a pack of $52$ cards two cards are drawn in succession one by one without replacement. The probability that both are aces is
One card is drawn from a well shuffled deck of $52$ cards. If each outcome is equally likely, calculate the probability that the card will be not a diamond.
One card is drawn from a well shuffled deck of $52$ cards. If each outcome is equally likely, calculate the probability that the card will be a black card (i.e., a club or, a spade)
One card is drawn from a well shuffled deck of $52$ cards. If each outcome is equally likely, calculate the probability that the card will be not a black card.
If two balanced dice are tossed once, the probability of the event, that the sum of the integers coming on the upper sides of the two dice is $9$, is
