A Jar contains 2 red marbles,3 blue marbles, and 1 green marble. What is the probability of slecting a red marble?

The probability would be 2/6

Step-by-step

there are 6 marbles in all

2 of them are red

2 out of the 6 are red

making the fraction 2/3 (or 1/3)

hope this helped!

1/3.

Step-by-step explanation:

There are 2 red marbles out of a total of  6 marbles in the jar.

Probability of selecting a red marble = 2/6 = 1/3..

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
