Question

in a game the player wins if he rolls a 4 on a number cube if the numbered cube is rolled 24 times then what is the reasonable prediction for the number of unsuccesful rolls

Answer 1

If you roll a numbered cube once, your chance of getting a 4 is 1/6. If you roll twice, your chance of getting a 4 is 2/12. If you roll three times, your chance of getting a 4 is 3/18. You see the pattern here? Try it yourself and see if you can get it! If you can't understand it, let me know and I'll give you the answer!
