A hat contains 5 red balls, 14 green balls, and 11 yellow balls. Alexa chooses one ball at random from the hat. What is the probability that Alexa chooses a yellow or green ball?

A) 5/6
B) 1/6
C) 7/15
D) 11/30

The answer is A) 5/6

Step-by-step explanation:

first you add all the balls together

30

then you add just the yellow and green balls together

25

the fraction would be 25/30

simplify it and you get 5/6

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
