Probability problems.
Independent Events. Two events, A and B, are independent if the outcome of A does not affect the outcome of B. In many cases, you will see the term, "With replacement ". As we study a few probability problems, I will explain how "replacement" allows the events to be independent of each other. Let's take a look at an example.

The experimental probability of an event is an estimate of the theoretical (or true) probability, based on performing a number of repeated independent trials of an experiment, counting the number of times the desired event occurs, and finally dividing the number of times the event occurs by the number of trials of the experiment. For example, if a fair die is rolled 20 times …What is the probability that the problem is solved? Sol: Probability of the problem getting solved = 1 – (Probability of none of them solving the problem) Probability of problem getting solved = 1 – (5/7) x (3/7) x (5/9) = (122/147) Example 9: Find the probability of getting two heads when five coins are tossed.
Twenty problems in probability. This section is a selection of famous probability puzzles, job interview questions (most high-tech companies ask their applicants math questions) and math competition problems. Some problems are easy, some are very hard, but each is interesting in some way.
Take a guided, problem-solving based approach to learning Probability. These compilations provide unique perspectives and applications you won't find anywhere else. The generation of test vectors is a key technique that affects the efficiency and fault detection rate of the boundary scan test. Aiming at the local optimal solution problem … 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. Probability problems are very important for the JEE exams. Probability talks about the outcome of an experiment. When you toss a coin, the outcome will be either heads or tails. The probability of an …

The Multiplication Rule. This is also called the AND Rule from which dependent and independent events can be calculated. The probability that two events A and B will occur in sequence is. The probability that events A and B and C will occur is given by. P(A and B and C) = P(A) × P(B/A) × P(C/A and B) P ( A and B and C) = P ( A) × P ( B / A ...
