These problems are called binomial probability problems. Since these problems were researched by Swiss mathematician Jacques Bernoulli around 1700, they are also called Bernoulli trials. We give the following definition: Solution: The sum of probabilities of all the sample points must equal 1. And the probability of getting a head is equal to the probability of getting a tail. Therefore, the probability of each sample point (heads or tails) must be equal to 1/2. Example 2 Let's repeat the experiment of Example 1, with a die instead of a coin.

The following exercises deal with our version of the game blackjack. In this card game, players are dealt a hand of two cards from a standard deck. The dealer’s cards are dealt with the second card face up, so the order matters; the other players’ hands are dealt entirely face down, so order doesn’t matter.Probability problems play a crucial role in the JEE exams. The concept of probability deals with the possible outcomes of an experiment. For instance, if you flip a coin, the possible outcomes are heads or tails. The likelihood of a certain outcome is determined by dividing the number of occurrences of that outcome by the total number of events.The chances for getting a coin and getting a Heads, it would be the addition of the chances of getting a Fair coin and getting a Heads, plus the chances of getting an Unfair coin and getting a Heads.
