How do you separate marbles and pebbles?
Well, darling, if you want to separate marbles and pebbles, you can simply use a sieve or mesh screen with holes big enough for the pebbles to pass through but small enough to catch those sassy marbles. Just give it a good shake and watch those marbles roll into one pile and the pebbles into another. Easy peasy lemon squeezy!
What does without replacement mean in probability?
Im not good at explaining things but here's an example. If I have 5 red marbles and 6 blue marbles in a bag and I pick one out. I then choose another marble without returning the first marble to the bag. Hope this helps.
How many marbles fit in a pint jar?
Well, isn't that a happy little question! It all depends on the size of the marbles, friend. You can start by gently placing a few marbles in the jar at a time, arranging them with care. Take your time, enjoy the process, and soon you'll have a lovely jar full of marbles that brings you joy.
If a bag contains three red and three blue marbles and if three marbles are chosen without replacement what is the probability that they will be all red or all blue?
There are 6!/3! = 120 possible combinations of marble colour. Of these, only 2 are "good". This gives a probability of 2/120 = 1/60 = 0.0167, or about one and two-thirds of a percent.
How do you use the displacement method to find the volume of an irregularly shaped object?
Half fill a graduated glass beaker with water and note the level. Place irregularly shaped object into the beaker. Note the new level. The difference between the two levels is the volume of the object. cw: OK, that method works for objects that don't get wet -- like steel. Tissue paper would not be a good candidate. Also, if the object floats, you have to submerge the object.
