1 |
Problem |
A bag contains 5 green and 7 red balls. Two balls are drawn. Find the probability that one is green and the other is red by using multiplication theorem.? |
|
2 |
Step |
probability of green ball. |
P(A) = \$\frac(1)(5)\$ |
3 |
Step |
probability of red ball. |
P(B) = \$\frac(1)(7)\$ |
4 |
Formula: |
Multiplication Theorem ⇒ \$P(A∩B) = P(B) × P(A)\$ |
|
5 |
Step |
Simplification. |
\$\frac(1)(7)\times\frac(1)(5)\$ |
6 |
Step |
After simplification we get. |
\$\frac(1)(35)\$ |
