One card is drawn from each of two ordinary packs of $52$ cards. The probability that at least one of them is an ace of heart, is
$\frac{{103}}{{2704}}$
$\frac{1}{{2704}}$
$\frac{2}{{52}}$
$\frac{{2601}}{{2704}}$
A coin is tossed. If the out come is a head, a die is thrown. If the die shows up an even number, the die is thrown again. What is the sample space for the experiment?
In a single throw of two dice what is the probability of getting a total $13$
Three coins are tossed once. Find the probability of getting $3 $ heads
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 $P($ not $3)$
The probability of $A, B, C$ solving a problem are $\frac{1}{3},\,\frac{2}{7},\,\frac{3}{8}$ respectively. If all the three try to solve the problem simultaneously, the probability that exactly one of them will solve it, is
