Given parameters:
Number of equally sized slices = 10
Red slices = 2
Yellow slices = 4
Blue slices = 4
Unknown:
Probability that the dial stops on a red or yellow color =?
Solution:
Probability is the likelihood of an event to occur.
Probability = [tex]\frac{Possible outcome }{Total outcome}[/tex]
This probability cites a mutually exclusive event because if the dial stops on red, it cannot be on yellow.
Pr(red or yellow) = Pr(red) + Pr(Yellow)
= [tex]\frac{2}{10}[/tex] + [tex]\frac{4}{10}[/tex]
= [tex]\frac{6}{10}[/tex]
= [tex]\frac{3}{5}[/tex]
The probability of red or yellow is [tex]\frac{3}{5}[/tex]
