13. probability the spinner has two equal sections, blue (b) and red (r). use the square of a sum to determine the possible combinations of spinning the spinner two times.

13. probability the spinner has two equal sections, blue (b) and red (r). use the square of a sum to determine the possible combinations of spinning the spinner two times.

Answer

Explanation:

Step1: List all possible outcomes

When spinning the spinner once, the outcomes are B (blue) and R (red). When spinning it twice, we consider all pairs. The first - spin has 2 possibilities and for each of these, the second - spin has 2 possibilities.

Step2: Calculate the combinations

We can use the multiplication principle. The possible combinations are (B, B), (B, R), (R, B), (R, R).

Answer:

(B, B), (B, R), (R, B), (R, R)
