A jar contains 2 red, 5 green, 2 blue and 6 yellow marbles. A marble is chosen at random from the jar. After replacing it, a second marble is chosen. What is the probability of choosing a green and then a yellow marble?​​

Step-by-step explanation:

S={sample space}

S(n)={2+5+2+6}

=15

G={members of green marble}

G(n)={5}

P(G)=probability of green marble

P(G)=5/15

=1/3

yellow marble

P(y)=6/15

probability of choosing a green and yellow marble

P(G and Y)=5+6=11

=11/15

ratio is 2 : 9

the answer is three

13.5 : 3
