Marco created a table to help him represent the sample space of spinning a spinner and flipping a coin. Result of spin Result of
1 answer:
The probability that the result is green - tail is 1/6.
Spinner has three colors that are red, green and yellow and coin has two sides that are head or tail.
<h3>What is the formula for probability?</h3>Divide the number of events by the number of possible outcomes
The sample space is,In total there are 6 ways to combine different colors with coin sides.
Therefore ,the probability that the result is green - tail is 1/6.
