a. 5/13
b. 10/13

anonymous · Answer

Because in a there are 5 possible options and in b there are 10.

anonymous · Answer

That is what I thought, however when I look it up it is 2/5 and 4/5. I need to show work to complete it.

anonymous · Answer

hmm, I don't know you you get that, but OK.

anonymous · Answer

given that you're dealt 2 cards, you have 50 left
there are 20 cards between 6 and 10 (4 cards for each number)
a) 20/50 = 2/5

same concept for b
b) 40/50 = 4/5
