If x is to be chosen at random from the set {1, 2, 3, 4} and y is to be chosen at random from the set {5, 6, 7}, what is the probability that xy will be even?	Choose the most appropriate option
A) 1/6  B) 1/3  C) 1/2  D) 2 by 3  E) 5/6
In order to make even nos. by multiplication,   we should have even * odd, odd * even or even * even   Total even nos. possible by multiplying nos. from the 2 sets:   (1*6);   2* any of the three from Set B;   3*6;&amp;   4* any of the three from set B    1+3+1+3=

<output>8</output>
8   Total possibilities=4 * 3= 
<gadget id="calculator">4 * 3</gadget>
<output>12</output>
12   P(event)=8/12 or 2/3   Ans 2 by 3
<result>D</result>
