Question

Someone please help me with this problem, I have tried multiple times but still couldn't get the correct answer. :(

Answer 1

We have the next situation

First, we must find the probability that the first spin lands on blue:

$P=\frac{4}{8}$

Then, we must find the probability that the second spin lands on gray:

$P=\frac{4}{8}$

So, te total probabilty is:

$P=\frac{4}{8}\cdot\frac{4}{8}=\frac{16}{64}=\frac{1}{4}$
