Answer:
P( blue or red ) = [tex]\frac{16}{21}[/tex].
Step-by-step explanation:
Given : You randomly draw a marble from a bag of marbles that contains 8 blue marbles, 5 green marbles, and 8 red marbles.
To find : what is p(draw a blue or red marble).
Solution : We have given that
A beg contain blue marble = 8 .
Green marble = 5.
Red marble = 8 .
Total marble = 8 + 5 + 8 = 21.
Probability = [tex]\frac{Favpurable\ outcome}{Total\ outcome}[/tex].
Probability of draw blue = [tex]\frac{8}{21}[/tex].
Probability of draw red = [tex]\frac{8}{21}[/tex].
P( blue or red ) = [tex]\frac{8}{21}[/tex] + [tex]\frac{8}{21}[/tex].
P( blue or red ) = [tex]\frac{16}{21}[/tex].
Therefore, P( blue or red ) = [tex]\frac{16}{21}[/tex].
