good
jimthompson5910 (jim_thompson5910):
2 spaces that we want, out of 6 total
jimthompson5910 (jim_thompson5910):
so 2/6 = 1/3 is the probability of landing on either one
jimthompson5910 (jim_thompson5910):
multiply this probability by the number of spins to get your answer
OpenStudy (anonymous):
so what is the problem? multiply 2/6*1/3 ?

no
jimthompson5910 (jim_thompson5910):
you'll multiply 1/3 by the number of spins
OpenStudy (anonymous):
so is the answer 2?
jimthompson5910 (jim_thompson5910):
how many spins are there total?
OpenStudy (anonymous):
its 54 times its spins, so the answer is 18 right?
