If there are 35 red and blue marbles in a jar, and the ratio of red to blue marbles is 3:4, what is the probability that, drawing twice, you will select two red marbles if you return the marbles after each draw?	Select the correct option: A) 1/25 B) 2/25 C) 3/25 D) 4/25 E) 6/49
35 red and blue marbles in a jar, and the ratio of red to blue marbles is 3:4   So, 7x=35 ---&gt; x=5   Red marbles = 3*x = 3*5= 
<gadget id="calculator">3*5</gadget>
<output>15</output>
15   Blue marbles= 4*x = 4*5= 
<gadget id="calculator">4*5</gadget>
<output>20</output>
20   Prob to select a red marble= 15/35 = 3/7   Prob to select 2 red marbles with replacement = 3/7*2*7= 
<gadget id="calculator">3/7*2*7</gadget>
<output>6</output>
6/49   Hence, answer will be 6/49.
<result>E</result>
