Respuesta :
You would add the red marbles and green marbles together and which would be 7 the get the total marbles would be 9 so the answer would be 7/9 or 78%
Probability of randomly picking a yellow marble is [tex]\frac{2}{9}[/tex].
Probability of not picking a yellow marble is [tex]\frac{7}{9}[/tex].
What is probability?
Probability denotes the possibility of the outcome of any random event. The meaning of this term is to check the extent to which any event is likely to happen.
According to the question
A bag contains 4 red marbles, 3 green marbles, and 2 yellow marbles.
Probability of randomly picking a yellow marble is
Number of favorable outcomes = 2
Total number of favorable outcomes = 4 + 3 + 2 = 9
Probability of randomly picking a yellow marble is [tex]\frac{2}{9}[/tex].
Probability of not picking a yellow marble
= 1 - Probability of randomly picking a yellow marble
= 1 - [tex]\frac{2}{9}[/tex]
= [tex]\frac{9-2}{9}[/tex]
= [tex]\frac{7}{9}[/tex]
Probability of not picking a yellow marble is [tex]\frac{7}{9}[/tex].
Hence,
Probability of randomly picking a yellow marble is [tex]\frac{2}{9}[/tex].
Probability of not picking a yellow marble is [tex]\frac{7}{9}[/tex].
