a bag contains 4 blue marbles,6 red marbles, 10 yellow marbles and 6 green marbles.What is the probability of not drawing a red marble?
number of "not reds" is 20
so prob(not red) 20/26 = 10/13
or
prob(red) = 6/26 = 3/13
prob(not red) = 1 - 3/13 = 10/13
Well, let's do some calculations with a touch of humor, shall we? To find the probability of not drawing a red marble, we need to know the total number of marbles in the bag that are not red. So, we have blue, yellow, and green marbles as our non-red options.
The total number of non-red marbles is 4 blue + 10 yellow + 6 green = 20 marbles.
Now, to calculate the probability of not drawing a red marble, we need to divide the number of non-red marbles by the total number of marbles in the bag.
The total number of marbles in the bag is 4 blue + 6 red + 10 yellow + 6 green = 26 marbles.
So, the probability of not drawing a red marble is 20/26 = 10/13, which simplifies to approximately 0.769 or 76.9%!
Remember, this probability assumes you won't be pulling any tricks like swapping marbles with a sneaky clown. Stay honest!
To calculate the probability of not drawing a red marble, we need to find the total number of marbles in the bag and subtract the number of red marbles.
Total number of marbles = 4 (blue) + 6 (red) + 10 (yellow) + 6 (green) = 26
Number of red marbles = 6
Number of marbles not red = Total number of marbles - Number of red marbles = 26 - 6 = 20
Therefore, the probability of not drawing a red marble is 20/26, which can be simplified to 10/13.
To find the probability of not drawing a red marble, we need to find the total number of marbles in the bag and the number of marbles that are not red.
The total number of marbles in the bag is given by adding up the number of marbles of each color: 4 blue + 6 red + 10 yellow + 6 green = 26 marbles.
The number of marbles that are not red is obtained by subtracting the number of red marbles from the total number of marbles: 26 marbles - 6 red marbles = 20 marbles.
Therefore, there are 20 marbles in the bag that are not red.
To find the probability, we divide the number of favorable outcomes (not drawing a red marble) by the total number of possible outcomes (all marbles in the bag).
So, the probability of not drawing a red marble is: 20 marbles / 26 marbles.
Simplifying the fraction, we have:
Probability = 20/26 = 10/13.
Therefore, the probability of not drawing a red marble is 10/13.
