The number $1,\,2,\,3$ and $4$ are written separately on four slips of paper. The slips are put in a box and mixed thoroughly, A person draws two slips from the box, one after the other, without replacement. Describe the sample space for the experiment.
If $1$ appears on the first drawn slip, then the possibilities that the number appears on the second drawn slip are $2,\,3,$ or $4 .$ Similarly, if $2$ appears on the first drawn slip, then the possibilities that the number appears on the second drawn slip are $1,\,3,$ or $4 .$ The same holds true for the remaining number too.
Thus, the sample space of this experiment is given by
$S=\{(1,2),\,(1,3)$, $(1,4),\,(2,1)$, $(2,3),\,(2,4),\,(3,1),\,(3,2)$, $(3,4),\,(4,1)$, $(4,2),\,(4,3)\}$
Cards are drawn one by one without replacement from a pack of $52$ cards. The probability that $10$ cards will precede the first ace is
The probability of obtaining sum ‘$8$’ in a single throw of two dice
The chance of getting a doublet with $2$ dice is
The chance of throwing a total of $7$ or $12$ with $2$ dice, is
Three coins are tossed. Describe Two events, which are not mutually exclusive.
