Question

(Theoretical Probability LC)

The following sample space could represent which repeated experiment?

S: {BY, YB, BB, YY}
Flipping a fair coin once
Rolling a number cube twice
Spinning a spinner once with 2 equal sections colored blue and yellow
Spinning a spinner twice with 2 equal sections colored blue and yellow

Answer 1

The sample space S: {BY, YB, BB, YY} represents the outcomes of spinning a spinner twice, where each section of the spinner is equally colored blue and yellow.

- BY means the first spin resulted in blue and the second spin resulted in yellow.
- YB means the first spin resulted in yellow and the second spin resulted in blue.
- BB means both spins resulted in blue.
- YY means both spins resulted in yellow.

This matches the scenario of spinning the spinner twice.

So the correct option is: **Spinning a spinner twice with 2 equal sections colored blue and yellow.**
