<em>We know that two odd numbers make an even number and two even numbers make another even number. </em><span><em>So out of the first choice you have a 7/15 chance of getting it even and an 8/15 chance of getting it odd. </em></span>
<span><em>If you get the first one even, then the second one MUST also be even so you multiply 7/15 with itself. </em></span>
<span><em>If you get the first one odd, then the second one MUST also be odd so you multiply 8/15 with itself as well. </em></span>
<span><em>You should have: </em></span>
<span><em>(7/15) x (7/15) </em></span>
<span><em>and </em></span>
<span><em>(8/15) x (8/15) </em></span>
<span><em>By multiplying the top portions with each other and the bottom portions with each other you get: </em></span>
<span><em>49/225 and 64/225 respectively. </em></span>
<span><em>Add both fractions together to get your answer. </em></span>
<span><em>Your answer should be (64+49)/225 = 113/225 </em></span>
