There are 70 marbles in the bag. the bag has 39 green? marbles, 24 red? marbles, and 7 yellow marbles. sasha selects a marble from the bag 20? times, and of those she picks a yellow marble 14 times. what is the experimental probability of selecting a yellow ? marble?

14/20

Explanation:

Sasha tried to get a marble 20 times. 14 of those times she got a yellow marble.

The experimental probability, which is the probability of choosing a yellow marble when Sasha actually tries choosing marbles from the bag.

The theoretical probability is based on the chance that Sasha will get a yellow marble, 7/70, is from the amount of marbles in the bag of yellow colour.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
