In a single throw of two dice, the probability of obtaining a total of $7$ or $9$, is
$\frac{5}{{18}}$
$\frac{1}{6}$
$\frac{1}{9}$
None of these
Two dice are thrown. The events $A, B$ and $C$ are as follows:
$A:$ getting an even number on the first die.
$B:$ getting an odd number on the first die.
$C:$ getting the sum of the numbers on the dice $\leq 5$
Describe the events not $B$
Out of $60 \%$ female and $40 \%$ male candidates appearing in an exam, $60\%$ candidates qualify it. The number of females qualifying the exam is twice the number of males qualifying it. A candidate is randomly chosen from the qualified candidates. The probability, that the chosen candidate is a female, is.
If a coin be tossed $n$ times then probability that the head comes odd times is
A die is thrown, find the probability of following events: A number less than $6$ will appear,
A coin is tossed. If it shows a tail, we draw a ball from a box which contains $2$ red and $3$ black balls. If it shows head, we throw a die. Find the sample space for this experiment.
