A bag contains 2 red, 5 blue, and 3 green marbles. A marble is chosen at random. What is the probability of NOT choosing a red marble​

Respuesta :

Step-by-step explanation:

  1. Number of red = 2
  2. Number of blue = 5
  3. Number of green = 3
  • total number of marbles = 10

probability of not choosing a red marble = 1--choosing a red marble.

Because probability is always one(1).

Probability =

[tex]1 - \frac{2}{10} [/tex]

[tex] \frac{8}{10} [/tex]

[tex] \frac{4}{5} [/tex]

Is the probability of not choosing a red marble.
