If there are 30 red and blue marbles in a jar, and the ratio of red to blue marbles is 2:3, what is the probability that, drawing twice, you will select two red marbles if you return the marbles after each draw?	Select
A) 1/25  B) 2/25  C) 3/25  D) 4/25  E) 21/25
0 red and blue marbles in a jar, and the ratio of red to blue marbles is 2:3   So, 5x=30 ---&gt; x=6   Red marbles = 2*x = 2*6= 
<gadget id="calculator">2*6</gadget>
<output>12</output>
12   Blue marbles= 3*x = 3*6= 
<gadget id="calculator">3*6</gadget>
<output>18</output>
18   Prob to select a red marble= 12/30 = 2/5   Prob to select 2 red marbles with replacement = 2/5*2*5= 
<gadget id="calculator">2/5*2*5</gadget>
<output>4</output>
4/25   Hence, answer will be 4/25.
<result>D</result>
