To determine the probability of landing on a black piece after spinning the spinner once, you need to know the total number of possible outcomes and the number of favorable outcomes (landing on a black piece).

Let's say the spinner has 8 equally likely sections, and one of those sections is black. In this case, the probability would be:


Probability = Number of Favorable Outcomes * Total Number of Outcomes

Probability = Total Number of Outcomes


Number of Favorable Outcomes

In this scenario:

Probability = 1 black section * 8 total sections

Probability = 8 total sections


1black section

So, the probability of landing on a black piece after spinning the spinner once is 1 * 8
