two 100 multiples of 7 are chosen at random, and 300 multiples of 8 are chosen at random. approximately what percentage of the 500 selected numbers are odd?	Choose the correct choice from the following answers:
A) 20 % B) 25 % C) 40 % D) 50 % E) 80 %
<gadget id="calculator">100 / 500</gadget>
<output>1/5 = around 0.2</output>

<gadget id="calculator">(1/5) * 100</gadget>
<output>20</output>

<result>A</result>
two 100 multiples of 7 are chosen at random, and 300 multiples of 8 are chosen at random. approximately what percentage of the 500 selected numbers are odd?
multiply(divide(100, 500), const_100)
two hundred multiples of seven will have 100 even and 100 odd numbers 300 multiples of eight will have all even ( being multiple of 8 ) probability of number selected being odd = total odd numbers / total available numbers probability = 100 / 500 = 0.2 = 20 % answer : option a
