For any event $A$
$P(A) + P(\bar A) = 0$
$P(A) + P(\bar A) = 1$
$P(A) > 1$
$P(\bar A) < 1$
(b) It is obvious.
A letter is chosen at random from the word $\mathrm {'ASSASSINATION'}$. Find the probability that letter is a vowel.
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
For independent events ${A_1},\,{A_2},\,……….,{A_n},$ $P({A_i}) = \frac{1}{{i + 1}},$ $i = 1,\,\,2,\,……,\,\,n.$ Then the probability that none of the event will occur, is
Two dice are thrown. If first shows $5$, then the probability that the sum of the numbers appears on both is $8$ or more than $8$, 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 a black card (i.e., a club or, a spade)
