The probability distribution of number of heads in two tosses of a coin is:

A die is rolled thrice. What is the probability of getting a number greater than 4 in the first and the second throw of dice and a number less than 4 in the third throw?

If the random variable X has the following distribution:

Match List-I with List-II:

Choose the correct answer from the options given below:

Let X denote the number of hours you play during a randomly selected day. The probability that X can values x has the following form, where c is some constant.

Match List-I with List-II

Choose the correct answer from the option given below.

A random variable X has the following probability distribution:

Then the value of C is:

The random variable X has a probability distribution P(X) of the following form, where k is some number.

A pair of dice is thrown, getting a total of 7 is considered a success.
Then the probability of success in a single throw is:

The probability distribution of number of heads in two tosses of a coin is:

The probability distribution of a random variable X is given under:

Then P(X≥4) is:

A random variable X has the following probability distribution where k is some number:

Find value of k.

A pair of dice is thrown 5 times. If getting a total of 7 is considered a success, then the probability of at least 3 successes is:
