The spinner has a total of 7 numbers, from 3 to 9.
The numbers that are less than 6 are the numbers 3, 4 and 5 (three numbers).
So the probability of the spinner landing on a number less than 6 is P1 = 3/7.
Then, the probability of the spinner landing on a 3 is P2 = 1/7 (just one number three among 7 options).
So the final probability is:
