Option A

$P=\frac{1}{12}$

Step-by-step explanation:

Note that the first spinner has 3 equal sections. Then there are 3 possible results for the first spinner

So the probability of getting a 2 is:

$P_1 = \frac{1}{3}$

Note that the second spinner has 4 equal sections. Then there are 4 possible results for the second spinner

So the probability of getting a 2 is:

$P_2 = \frac{1}{4}$

Now, as they are independent events, then the probability of getting a 2 in both spinners is:

P = P_1 * P_2

Finally

$P=\frac{1}{3}*\frac{1}{4}\\\\P=\frac{1}{12}$
