Question

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?​​

Answer 1

The answe wound be 4 outa of 16

Answer 2

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
