A ball is taken from a bag and then replaced. the relative frequency of getting a red ball is 0-6. if the bag contains 15 balls, how many of them are not red?
0.6 * 15 = 9
so, 15-9 = 6 are not red
The relative frequency of getting a red ball is 0.6, which means that 60% of the balls in the bag are red.
Let's calculate the number of red balls in the bag:
0.6 * 15 balls = 9 balls
If there are 15 balls in total and 9 of them are red, the number of balls that are not red can be calculated by subtracting the number of red balls from the total number of balls:
15 balls - 9 red balls = 6 balls
Therefore, there are 6 balls in the bag that are not red.
To find the number of balls that are not red, we need to know the total number of balls and the relative frequency of getting a red ball.
The relative frequency is calculated by dividing the number of times the event occurs (getting a red ball) by the total number of trials (the number of times the ball is taken).
In this case, the relative frequency of getting a red ball is given as 0.6. We can interpret this value as 60% or 6 out of every 10 balls being red.
Let's assume there are a total of 100 balls. Since 6 out of 10 balls are red, we can calculate the number of red balls as (6/10) * 100 = 60.
Now, we can use this proportion to find the number of red balls in a bag containing 15 balls.
(6/10) * 15 = 9
So, if the relative frequency of getting a red ball is 0.6, then we can expect that approximately 9 out of 15 balls are red.
To find the number of balls that are not red, we subtract the number of red balls from the total number of balls in the bag:
15 - 9 = 6
Therefore, 6 balls in the bag are not red.
