A spinner has 10 equally sized sections, 8 of which are gray and 2 of which are blue. The spinner is spun twice. What is the probability that the first spin lands on gray and the second spin lands on blue ?

probability of landing on grey:
8/10 = 80/100 = 80%

probability landing on blue:
2/10 = 20/100 = 20%

-probability of landing on a grey on first spin is 80%
-probability of landing on a blue on second spin is 20%  
It would be 8-2
Because(out of 10) 8 means 80%
And 2 means 20%
It would end up to be 80%-20%
