Answer:

1/9

Explanations:

Probability is the likelihood or chance that an event will occur. Mathematically;

Probability = expected outcome/Total outcome

The total number on the spinner is given as:

S = {1, 2, 3}

Total outcome = 3

If the spinner land on a number less than 2, hence the expected outcome is 1

Pr(spinner land on a number less than 2) = 1/3

If the spinner lands on a 2, the probability that it lands on a 2 will be expressed as:

Pr(spinner lands on a two) = 1/3

Pr( landing on a number less than 2 and then landing on a 2​) = 1/3 * 1/3 = 1/9

Hence the probability of landing on a number less than 2 and then landing on a 2​ is 1/9
