A coin is tossed $3$ times by $2$ persons. What is the probability that both get equal number of heads
A die is thrown repeatedly until a six comes up. What is the sample space for this experiment ?
Describe the sample space for the indicated experiment: A coin is tossed and then a die is rolled only in case a head is shown on the coin.
Three coins are tossed. Describe Three events which are mutually exclusive but not exhaustive.
Two persons each make a single throw with a die. The probability they get equal value is ${p_1}$. Four persons each make a single throw and probability of three being equal is ${p_2}$, then
