There are 30 red marbles, 16 blue marbles, and 14 green marbles in a jar. What is the probability of picking out a red marble without looking?
30%
50%
23%
0 27%

B or 50%

Step-by-step explanation:

First, you add all of them together

30 + 16 + 14 = 60

Then you do the part/whole

30/60 = 1/2

1/2 = 50%

x=60

Step-by-step explanation:

So basically the sum of interior angle of a triangle is 180.

Add all the values and make it equal to 180.

x+3/2x+1/2x=180

Then find x

3x=180

x=180/3

x=60 degrees
