Final answer:
To find the probability that both spins are blue, multiply the probability of the first spin being blue by the probability of the second spin being blue.
Step-by-step explanation:
The probability that both spins are blue can be found by multiplying the probability of the first spin being blue by the probability of the second spin being blue. Let's use P(B1) to represent the probability of the first spin being blue and P(B2) for the probability of the second spin being blue. Given the information, P(B1) = 2 and P(B2) = x. So, the probability that both spins are blue is P(B1) * P(B2) = 2 * x = 2x.
