In each of the following experiments specify appropriate sample space A person is noting down the number of accidents along a busy highway during a year.
The number of accidents along a busy highway during the year of observation can be either $0$ (for no accident) or $1$ or $2,$ or some other positive integer. Thus, a sample space associated with this experiment is $S =\{0,1,2, \ldots\}$
From a pack of $52$ cards, two cards are drawn one by one without replacement. The probability that first drawn card is a king and second is a queen, is
A box containing $4$ white pens and $2$ black pens. Another box containing $3$ white pens and $5$ black pens. If one pen is selected from each box, then the probability that both the pens are white is equal to
Two card are drawn successively with replacement from a pack of $52$ cards. The probability of drawing two aces is
An experiment consists of tossing a coin and then throwing it second time if a head occurs. If a tail occurs on the first toss, then a die is rolled once. Find the sample space.
One die of red colour, one of white colour and one of blue colour are placed in a bag. One die is selected at random and rolled, its colour and the number on its uppermost face is noted. Describe the sample space.
