You take one ball randomly from a bag with 10 yellow, 5 orange and 5 green balls. What is the probability that you take a yellow ball. 1

1/4

10/15
1/2

1/2

Step-by-step explanation:

The probability of taking a yellow ball can be found by dividing the number of yellow balls over the total number of balls.

P(yellow ball)= yellow balls / total balls

There are 10 yellow balls. There are a total of 20 balls. There are 20 because there are 10 yellow, 5 orange, and 5 green. When 10, 5, and 5 are added, the result is 20.

yellow balls = 10

total balls= 20

P(yellow ball)= yellow balls / total balls

P(yellow ball)= 10/20

The fraction 10/20 can be simplified. Both the numerator( top number) and denominator (bottom number) can be evenly divided by 10.

P(yellow ball)= (10/10) / (20/10)

P(yellow ball)= 1/(20/10)

P(yellow ball)= 1/2

The probability of taking a yellow ball is 1/2.
