Independent Events:
A number cube is rolled twice. Compare the following problems.
1. Find the probablity that the first roll is 4 and the secnd roll os even.
2. Find the probablity that the first roll iss 4 or the second roll is even.
Conditional Probability:
1. A bag contains 9 red marbles and 3 green marbles. How can you find the probability of drawing first one green marble and then one red marble if you do not replace the first marble?
chance you roll a 4 is 1/6, chance it is even is 1/3
1. 1/6 * 1/3 = 1/18 chance
2. 1/6 + 1/3 = 1/2 chance
