Answer:x=18

How many favorable outcomes will there be for spinning blue at least once? <br> (I NEED HELP PLEASE)
Westkost [7]

Answer:

It depends on the spinner and how many of each color spaces are on it.

Step-by-step explanation:

A favorable outcome means an outcome that matches your criteria.

Example: You spin a spinner with 10 spaces. 3 blue, 2 red, 3 green, 2 yellow.

If you spin the spinner once, there are 3 favorable outcomes (remember a favorable outcome means landing on blue in this case).

Spinning the spinner twice would lead to at least 100 outcomes, 9 of which are favorable.
