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 diamond
When a card is drawn from a well shuffled deck of $52$ cards, the number of possible outcomes is $52$
Let $A$ be the event ' the card drawn is a diamond ' Clearly the number of elements in set $A$ is $13 .$
Therefore, $P ( A )=\frac{13}{52}=\frac{1}{4}$
i.e. probability of a diamond card $=\frac{1}{4}$
The probability of happening of an impossible event i.e. $P\,(\phi )$ is
If $A$ and $B$ are mutually exclusive events, then the value of $P (A$ or $B$) is
The probability that in a year of the $22^{nd}$ century chosen at random there will be $53$ Sundays is
