The probability of two independent events is P(A) * P(B) for event A and B. 

The probability of hitting either is 1/10, thus the probability of both is 1/100

cwrw238 · Answer

for one spin probability of a 2 is 1/10  as there are 10 equal sections
the probability of a 4 is ask 1/10

as these events are independent the probabilities are multiplied 
so the probability of 2 then 4 = 1/10 * 1/10 = 1/100 or 0.01
