Two dice are thrown together. The probability that sum of the two numbers will be a multiple of $4$ is
$\frac{1}{9}$
$\frac{1}{3}$
$\frac{1}{4}$
$\frac{5}{9}$
An experiment consists of rolling a die and then tossing a coin if the number on the die is even. If the number on the die is odd, the coin is tossed twice. Write the sample space for this experiment.
From a well shuffled pack of cards one card is drawn at random. The probability that the card drawn is an ace is
Two dice are thrown. The probability that the sum of the points on two dice will be $7$, is
A bag contains $9$ discs of which $4$ are red, $3$ are blue and $2$ are yellow. The discs are similar in shape and size. A disc is drawn at random from the bag. Calculate the probability that it will be blue
Two coins are tossed. Let $A$ be the event that the first coin shows head and $B$ be the event that the second coin shows a tail. Two events $A$ and $B$ are
