Help on Probability Formula

Introduction to probability formulas help:
Probability formula is one of the most important parts in the mathematics. Consider the example; a card is drawn from the set of cards. Probability is the way for expressing the event.The formula includes the process of finding the probability for the normal event and the mutually exclusive event. The probability theory is used in the field of mathematics and the statistics.

Formula - Probability Formulas Help:

• The formula used to predict the probability for any event A is P (A) = number of favorable cases/ total number of cases.
• P (A’ ) + P (A) = 1
• P(S) =1, where S determines the sample space.
• P( A U B) = P(A) + P( B), A and B are called the mutually exclusive events.
• If A, B are any events then P( A U B) = P(A) + P( B) - P(A ∩ B)
• P (A ∩ B) = P (A) P (B), A and B are called as the independent to each other events that means the independent event. This could also help us on rate of change formula

Example Problems for Probability Formulas Help:
Example 1 for probability formulas help:
The events A and B are mutually exclusive event and P (A) = 0.35 and P (B) = 0.56. Calculate the value for P (A U B).
Solution:
Given that P (A) = 0.35 and P (B) = 0.56. We have to find the value for P (A U B).
The formula used to find P (A U B) if A and B are mutually exclusive event is
P (A U B) = P (A) + P (B)
P (A U B) = 0.35 + 0.56
P (A U B) = 0.91
The value for P (A U B) is 0.91.
