Leon has a bag of 4 red balls, 3 green balls and 6 yellow balls. He takes a ball out and replaces it 50 times. Out of those 50 trials he pulls out a green ball 12 times. What is the experimental probability of getting a green ball on his next trial?
same as the first time: 6/13
To find the experimental probability of getting a green ball on Leon's next trial, we need to divide the number of successful outcomes (getting a green ball) by the total number of trials.
In this case, Leon conducted 50 trials, and he got a green ball 12 times. So, the number of successful outcomes is 12.
To find the total number of trials, we need to consider that Leon replaces the ball after each trial. Since there are 4 red balls, 3 green balls, and 6 yellow balls, there are a total of 4+3+6 = 13 balls in the bag.
Since Leon replaces the ball after each trial, the number of balls in the bag does not change, which means there are still 4 red balls, 3 green balls, and 6 yellow balls.
Therefore, the total number of trials is 50.
Now, we can calculate the experimental probability of getting a green ball on Leon's next trial:
Experimental probability = (Number of successful outcomes) / (Total number of trials)
= 12 / 50
= 0.24
So, the experimental probability of getting a green ball on Leon's next trial is 0.24.
