Suppose $3$ bulbs are selected at random from a lot. Each bulb is tested and classified as defective $(D)$ or non-defective $(N)$. Write the sample space of this experiment?
$3$ bulbs are to be selected at random from the lot. Each bulb is tested and classified as defective $(D)$ or non-defective $(N)$.
The sample space of this experiment is given by
$S=\{ DDD ,\, DND ,\, DNN ,\, NDD , \,NDN , \,NND , \,NNN \}$
In a throw of three dice, the probability that at least one die shows up $1$, is
Two dice are thrown together. The probability that at least one will show its digit $6$ 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.
Two dice are thrown simultaneously. The probability of getting the sum $2$ or $8$ or $12$ is
A die is thrown, find the probability of following events: A number greater than or equal to $3$ will appear.
