Ok so, 

One bag of 5 red and 5 white balls.

Two were taken out of the bag, they didn't mention what color they were.

If there were 10 balls total, and 5 of them are red, how many red balls could have possibly been pulled out of the bag?

So, the probability that one ball was red is 1/5 because there are only 5 red balls in the bag. 

A) If it was replaced before the second draw, the probability would still be 1/5 because they put the red ball back.

B) If it was not replaced before the second draw, the probability would be 1/4 being that there are now only 4 red balls left in the bag.

A) If it was replaced before the second draw, the probability would still be 1/5 because they put the red ball back.

B) If it was not replaced before the second draw, the probability would be 1/4 being that there are now only 4 red balls left in the bag.

What is probability?

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Given that:-

  • One bag of 5 red and 5 white balls. Two were taken out of the bag, they didn't mention what color they were.

The probability will be calculated as follows:-

The probability that one ball was red is 1/5 because there are only 5 red balls in the bag.

A) If it was replaced before the second draw, the probability would still be 1/5 because they put the red ball back.

B) If it was not replaced before the second draw, the probability would be 1/4 being that there are now only 4 red balls left in the bag.
