probability examples

In this blog we will learn about probability examples,

Ex 1: What is the probability of getting a sum is 4 or 8 when throwing two dice simultaneously?

Solution:Now we will see how to solve probability examples

Let S = sample space, S = {(1, 1), (1, 2), (1,3)...(6, 5), (6, 6)}, n(S) = 36

A be the event of getting a sum is 4, n(A) = {(1, 3), (2, 2), (3, 1)} = 3

B be the event of getting a sum is 8, n(B) = {(2, 6), (3, 5), (4, 4), (5, 3), (6, 2)} = 5

P(A) = =

P(B) = =

P(A or B) = P(A) + P(B)

P(4 or 8) = + = .

In the next blog we will learn about linear definition and math dictionary algebra.Hope you like the above example of probability examples,please leave your comments if you have any doubts.
