A spinner is separated into 4 equal pieces, as shown below: A spinner is shown with four colors, yellow, pink, white, and black, marked on it. The arrow points towards the black color. Jonathan spins the spinner 10 times. What is the theoretical probability that it stops on the black sector on the last spin?

@cvliboi

OpenStudy (welshfella):

all these 10 spins are independent of each other...

OpenStudy (welshfella):

if we spinned it just once what is the probability of getting black?

@arminarlerts

OpenStudy (anonymous):

I would say 2/5 but are their any options?

OpenStudy (anonymous):

yeah 1/40,1/4,5/2,41/4

OpenStudy (anonymous):

just those

OpenStudy (welshfella):

what is the last one?

OpenStudy (welshfella):

oh ok i got it

OpenStudy (anonymous):

yeah

OpenStudy (welshfella):

well we are told nothing about what happens on the first 9 spins

OpenStudy (welshfella):

so i would say the required probability is the same as we would get on just one spin : - 1/4

OpenStudy (anonymous):

I think its B

OpenStudy (welshfella):

yes 1/4
