Okay, here we have this:

Considering the provided spinner and statement, we are going to calculate the requested probability, so we obtain the following:

So we have the following equation:

Probability of landing on a number less than 3 and then landing on a 2=Probability of landing on a number less than 3*Probability of landing on a 2

Probability of landing on a number less than 3 and then landing on a 2=(Numbers less than 3/Total numbers)*(Times 2 is present/Total number)

Replacing:

Probability of landing on a number less than 3 and then landing on a 2=(2/4)*(1/4)

Probability of landing on a number less than 3 and then landing on a 2=(2*1)/(4*4)

Probability of landing on a number less than 3 and then landing on a 2=2/16

Probability of landing on a number less than 3 and then landing on a 2=1/8

Probability of landing on a number less than 3 and then landing on a 2=12.5%

Finally we obtain that the probability of landing on a number less than 3 and then landing on a 2 is equal to 12.5%.
