The response from the other tutor shows a solution using one standard method -- selecting the balls one at a time, finding the probability that each successive draw gets a red ball, and …

pROBABILITY WITH REPLACEMENT ... probability Basics Above are 10 coloured balls in a box, 4 red, 3 green, 2 blue and 1 black. A ball is randomly selected. After each selection the balls …

Urn probability simulator This calculator simulates the urn (or box with colored balls) often used for probability problems, and can calculate probabilities of different events.

Now that we briefly understand dependent probability – before diving deep into calculating probability without replacement – let’s first try to visualize what dependent events are and how …

Mar 16, 2025 · A bag contains 5 red balls and 3 blue balls. Randomly select 2 balls from the bag without replacing them. What is the probability of selecting 1 blue ball and 1 red ball?

A box contains 5 red balls and 3 blue balls. Two balls are drawn at random without replacement. What is the probability that both balls are red?

An urn contains five balls, two are red and three are blue. Randomly select two balls sequentially without replacement and define events A: second ball is red, B: first ball is blue.

Five balls are randomly chosen, without replacement, from an urn that contains 5 red, 6 white, and 7 blue balls. Find the probability that at least one ball of each color is chosen.
