Abag contains 5 red marbles and 4 green marbles. what is the probability of choosing a red marble then a green marble, without replacement? a.) 25/81 b.) 5/18 c.) 25/72 d.) 20/81

Correct choice is B

Step-by-step explanation:

A bag contains 5 red marbles and 4 green marbles, 9 marbles in total.

The probability of choosing a red marble is

After choosing the red marble, 8 marbles left. Then the probability of choosing  a green marble is

Hence, the probability of choosing a red marble then a green marble, without replacement is

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.
