Abag of marbles contains 7 red, 5 blue, 4 green, and 2 yellow marbles. jon selects a marble, replaces it, then selects another marble. what is the probability that jon selects a red marble and then a yellow marble?

about 0.0432 or 4.32%

Step-by-step explanation:

Given : A bag of marbles contains 7 red, 5 blue, 4 green, and 2 yellow marbles.

Total marbles = 7+5+4+2=18

Let R : Event of getting first marble as red .

Y= Event of getting second marble as yellow.

Jon selects a marble, replaces it, then selects another marble.

⇒Both events are independent .

Probability of getting first marble as red =

Probability of getting second marble as yellow =

Now, the probability that Jon selects a red marble and then a yellow marble :

 [ ∵ Event R and Y are independent .]

Hence, the probability that Jon selects a red marble and then a yellow marble is about 0.0432 or 4.32%.
