OpenStudy (misty1212):

what is the probability you get any one question right?

OpenStudy (misty1212):

if you do not know, say so and i can tell you hint, there are 4 possible answers, only one is right

I really don't know..

OpenStudy (misty1212):

one is right, out of four ratio is \(\frac{1}{4}\) i.e. the probability you get any one answer correct is \(\frac{1}{4}\)

OpenStudy (misty1212):
