Question 1099493
<br>The number of different ways that 2 of the 5 pairs could be platinum is "5 choose 2" = 10.<br>
For each of those different ways, the probability of getting 2 platinum (probability 40% each) and 3 others (probability 60% each) is {{{(0.4)^2 * (0.6)^3 = 0.03456}}}<br>
So the probability of getting 2 platinum pairs out of 5 is {{{10*0.03456 = 0.3456}}}
