Probability problems

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.

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. 3.2: Problems on Conditional Probability.
