Question

anonymous · Answer

what is the probability that the first marble chosen is red?

anonymous · Answer

if that is not clear, let me know
you need that number first

anonymous · Answer

add all the marbles up, so thats 10 then you take red(2) and then blue(3) and i think you add them so it would be 5 so the probability of red and blue would be 5 out of 10. which is   $$\frac{ 5 }{ 10 }$$
