1 |
Problem |
A perfect die is tossed then what is the probability of throwing 3 or 5 by using addition thereom. |
|
2 |
Step |
Total number of events. |
6 |
3 |
Step |
probability of throwing 3 is. |
P(A) = \$\frac(1)(6)\$ |
4 |
Step |
probability of throwing 5 is. |
P(B) = \$\frac(1)(6)\$ |
5 |
Formula: |
Addition theorem ⇒ P (A ∪ B) = P (A) + P (B) |
|
6 |
Step |
Simplification. |
\$\frac(1)(6) + \frac(1)(6) = \frac(2)(6)\$ |
7 |
Step |
After simplification we get. |
\$\frac(1)(3)\$ |
