A bag contains 1 blue, 2 green, and 2 red marbles. You choose a marble with one hand and then a second marble with the other han
2 answers:
The probability of choosing a red marble is 2/5 while the probability of choosing a green marble after a red marble is 1/2
Data;
- blue = 1
- green = 2
- red = 2
To solve this problem, we have to do probability without replacement.
The total number of marbles in the bag is
The probability of choosing a red marble is
Number of read marbles = 2
probability of choosing a red marble is
The probability of choosing a green marble after a red marble is
The probability of choosing a red marble is 2/5 while the probability of choosing a green marble after a red marble is 1/2
