Please Help Me :( hallie is trying to win the grand prize on a game show. Should she try her luck by spinning a wheel with 6 equal sections labeled from 1 to 6 and hope she gets a 5, or should she roll two number cubes and hope she gets the same number on both cubes? Explain

OpenStudy (rulnick):

Equal probabilities, both 1/6.

OpenStudy (zzr0ck3r):

cubes have 6 sides and there are two of them, so the odds of getting the same on both are not 1/6

OpenStudy (rulnick):

Whatever first die produces, the probability second one matches it is 1/6.

OpenStudy (zzr0ck3r):

o I c

OpenStudy (zzr0ck3r):

sorry, good call

OpenStudy (rulnick):

Probability of getting 5 on wheel is 1/6. Same.

OpenStudy (zzr0ck3r):

I thought it asked the odds of getting a 5 on both the cubes:)

OpenStudy (rulnick):

reasonable :)
