In a throw of a dice the probability of getting one in even number of throw is
$\frac{5}{{36}}$
$\frac{5}{{11}}$
$\frac{6}{{11}}$
$\frac{1}{6}$
Describe the sample space for the indicated experiment : A die is thrown two times.
The event $A$ is independent of itself if and only if $P(A) = $
The probabilities of a student getting $I, II$ and $III$ division in an examination are respectively $\frac{1}{{10}},\,\frac{3}{5}$ and $\frac{1}{4}.$ The probability that the student fails in the examination is
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?
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.
