Question

There are 4 green bails, 3 purple bails, 2 orange balls, and 1 white ball in a box. One bail is randomly drawn and replaced, and

another ball is drawn
What is the probability of getting a aroon ball then a purple ball?

Answer 1

Basically you start with 10 balls. Since you have four green balls, the probability of picking that will be 4/10 or 2/5. Once you pick a green ball, there will be nine balls left. since there are 3 purple balls the probability of that will be 3/9 or 1/3. then you multiply the two probabilities to get the combined probability of 2/15
