If you draw 5 balls with replacement from an urn containing white balls and black balls is the probability of getting 3 white balls always higher than if you draw the balls without replacement?
The probability of getting 3 white balls in a draw of 5 balls with replacement from an urn containing white balls and black balls is always greater than the same test without replacement, because the number of white balls decreases when you draw a white ball and do not replace it. The ratio of white to black with replacement is constant, and is always less than one, assuming there is at least one black ball. The ratio of white to black without replacement decreases each turn, and is still less than one, and is less than the previous ratio, unless the question asked about 2 white balls or less.
A bag contains 3 red balls and 4 green balls randomly draw one ball then replace it and randomly draw a second what is the percentage?
Drawing one red ball out of a bag that contains 3 red balls and 4 green balls is 3 in 7. If we are to randomly select one ball out of the bag and replace it (I assume with the same ball) then there are still 3 red balls and 4 green balls. The odds are still 3 in 7. It doesn't matter how many times you draw. Every time you draw a ball you have a 3 in 7 chance of pulling out a red ball.
How do you do probabilities?
Example of probability is if you have 10 blue gumballs 5 pink gumballs and 3 orange gumballs the answer is 10 because the more gumballs you have is the one you will pick without looking if you still dont understand please comment below,thanks for all questions:)
Why 0 is rational number?
because it does not value Zero is considered rational because it can still be expressed as a fraction
What equals 23 over 60 on a test?
23/60 in a test still equals 23/60. Just because it is in a test does not change the fraction!23/60 in a test still equals 23/60.
