One card is drawn from a well shuffled deck of $52$ cards. If each outcome is equally likely, calculate the probability that the card will be not a black card.
When a card is drawn from a well shuffled deck of $52$ cards, the number of possible outcomes is $52$
The event 'card drawn is not a black card' may be denoted as $C'$ or 'not $C'$.
We know that $P$ (not $C$ ) $=1- P ( C )=1-\frac{1}{2}=\frac{1}{2}$
Therefore, probability of not a black card $=\frac{1}{2}$
A determinant is chosen at random. The set of all determinants of order $2$ with elements $0$ or $1$ only. The probability that value of the determinant chosen is positive, is
A coin is tossed until a head appears or until the coin has been tossed five times. If a head does not occur on the first two tosses, then the probability that the coin will be tossed $5$ times is
Let Ajay will not appear in JEE exam with probability $\mathrm{p}=\frac{2}{7}$, while both Ajay and Vijay will appear in the exam with probability $\mathrm{q}=\frac{1}{5}$. Then the probability, that Ajay will appear in the exam and Vijay will not appear is :
A fair coin is tossed repeatedly. If tail appears on first four tosses then the probability of head appearing on fifth toss equals
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.
