Title: Probability(dice) |
Grade: 9-a Lesson: S3-L3 |
Explanation: The best way to understand statistics is by looking at some examples. Take turns and read each example for easy understanding. |
Examples:
Two dice are thrown simultaneously then Find the probability of getting a doublet of odd numbers.
Step 1a
|
|
Assumption of probability |
|
Explanation: Let us assume probability of getting a doublet of odd numbers = P(E) |
|
Step 1b
|
|
Find the number of favorable outcomes,Total number of outcomes |
|
Explanation: Total number of outcomes = 36 Number of favorable outcomes = 3 The favourable outcomes are (1,1),(3,3),(5,5) |
|
Step 1c
|
|
Finding the probability |
|
Explanation: P(E) =\$"Number of favorable outcomes" / "Total number of possible outcomes"\$ P(E) = \$3/36\$ Probability of getting a doublet of odd numbers = \$1/12\$ |
