Ajar contains 2 red marbles, 3 blue marbles, and 1 green marble. What is the probability of

selecting a red marble?

Ajar has 6 marbles and 2 marbles. the probability of selecting a red marble is 2/6, or 1/3 when simplified

1/3

Step-by-step explanation:

total number of marbles: 2 + 3 + 1 = 6

number of red marbles = 2

The probability of an event is the number of desired outcomes divided by the total number of possible outcomes.

number desired outcomes: 2 since there are 2 red marbles, and either one is a desired outcome

total number of possible outcomes: 6

p (red) = 2/6 = 1/3

Answer: 1/3
