To do this, set up the ratio , where a favorable outcome is the event you are seeking to happen. [5] For example, if the first event is throwing a 3 with one die, the number of favorable outcomes is 1, since there is only one 3 on a die. The number of possible outcomes is 6, since a die has six sides.
WebExample 1: Finding a Conditional Probability on a Tree Diagram. A bag contains 3 blue balls and 7 red balls. Fares selects 2 balls without replacement and draws the following tree diagram. Given that the first ball is red, find the value of 𝑥 that represents the probability that the second ball selected is red. WebConditional Probability. The conditional probability, as its name suggests, is the probability of happening an event that is based upon a condition.For example, assume that the probability of a boy playing tennis in the evening is 95% (0.95) whereas the probability that he plays given that it is a rainy day is less which is 10% (0.1).
