Kevin Lee has a blue, red, and green tie. He also has a blue and green shirt. Find the probability that Kevin lee will choose to wear a red tie with his blue shirt. Dependent or independent
we have that
the probability that choose a a red tie is
P=1/3
the probabiity that choose a blue shirt is
P=1/2
so
the probability that choose to wear a red tie with his blue shirt is
P=(1/3)(1/2)
P=1/6 or P=16.67%
are independent events
