Question

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​

Answer 1

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 =

$1 - \frac{2}{10}$

$\frac{8}{10}$

$\frac{4}{5}$

Is the probability of not choosing a red marble.
