Question

So a spinner has 5 equally sized sections, 3 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?

Write the answer as a faction in simplest form.

Answer 1

The two spins are independent events.

 

Let A = the first spin lands on gray

 

      B = the second spin lands on blue

 

P(A and B) = P(A)P(B) = (3/5)(2/5) = 6/25
