Math Destroyer 2015 test 2 #35

Hard Work Pays Off

Leo the Lion says Ger
So the question asks : a bag contains 7 walnuts, 4 cashews, and 3 pistachio nuts..etc. it asks about the probability of getting one cashew and one walnut. the answer is 4/13 and I kind of know how to get there but there is another answer choice which is 28/91 and that value equals 4/13. like it is the same value, so why is the answer 4/13, if they both equal 0.30769231 ?

I'm not Nancy so I can't say for sure, but I think that's an error. I've got the 2016 math destroyer on me and the answer choice is 4/13 or 27/91, not 28
