How do you find probability example?
For example, if the number of desired outcomes divided by the number of possible events is . 25, multiply the answer by 100 to get 25\%. If you have the odds of a particular outcome in percent form, divide the percentage by 100 and then multiply it by the number of events to get the probability.

What is the probability of replacing a marble with another?
There is one important concept in problems with marbles/cards/balls. When the first marble is removed from a jar and not replaced, the probability for the second marble differs (9/99 vs. 10/100). Whereas in case of a coin or dice the probabilities are always the same (⅙ and ½).
How many marbles are drawn without replacement from the jar?
Two marbles are drawn without replacement from a jar containing 4 black and 6 white marbles. a) Draw the tree diagram for the experiment. A bag contains 5 blue balls and 4 red balls. A ball is picked and not replaced.
How do you sample two marbles in a box?
Consider a box containing 3 red, 2 blue, and 1 yellow marble. If we sample two marbles, we can do this either: ● without replacement of the first before the second is drawn. The highlighted branch represents a blue marble with the first draw and a red marble with the second draw.
What are the odds of getting a non yellow marble?
like Sal mentioned a 3/8th chance That is roughly 37.5\% chance of picking a yellow marble leaving a 62.5\% chance of picking a non yellow marble (those add up to 100\%)
