why am i coming to a lion game for math help? because there are people on here who are obviously really good at it with all the statistics and probability calculations i’ve seen floating around for stats and other stuff so hi this is a probability question if i have a spinner wheel divided into 4 equal sections ( A B C D ) and i want the wheel to land on section D, that’s a 25% chance of that happening, i know that HOWEVER does that probability change if i spin the SAME WHEEL 3 times instead of 1? like more spins obviously equals a better chance of landing on D at least once, but how do i calculate the percentage of that? tldr: wheel of 4 equal sections (ABCD) want to land on D = 25% chance of D per 1 spin spinning same wheel 3 times = __% of D i probably explained this badly LMAO but yeah  0 players like this post!

4 sections 3/4 (taking 1 off for it to not land on D) (3/4)^3 spins so it = 27/64 But you take 1 - 27/64, which is roughly 57.8% of D? 0 players like this post! Like? |

Hi! you didn't explain this badly at all. To calculate the percentage of getting D at least once, we gotta do the following - We know that
First, we gotta find the probability of not landing on D in all three spins, which would be 0.75*0.75*0.75 = (0.75)^3 = 0.421875. Next, we gotta find the probability of landing on D in all three spins, which would be 1-probabilty of no D in three spins, or 1-0.421875 which is 0.578125. Lastly, we multiply the probability by 100 to convert to percent, which gives us approximately 57.81%. So, if you spin a wheel three times, the probability of landing on D at least once is approximately 57.81%. 1 player likes this post! Like?Edited on 28/12/24 @ 11:21:24 by Arret Rea (#138617) |
