A fair spinner has 4 equal sections numbered 1, 2, 3 and 4. What is the probability of landing on 3? Give the probability as a fraction out of the four equal sections.

Explication

One of the four equal sections shows a 3, and equal sections are equally likely, so the spinner stops there in one spin out of four. Answering 3/4 would claim that three sections give the result, which would be true only of a spinner with the number 3 painted on three of its sections.
