Suppose that you roll a pair of fair dice. Give that you roll a sum of 7 on the first roll, what is the probability that you roll a sum of 7 on the second roll?

OpenStudy (anonymous):

the events are independent

OpenStudy (anonymous):

So would it be 5/36? I'm still confused

OpenStudy (anonymous):

i dont know i m still making the problem

OpenStudy (anonymous):

yo get a sum of 7 we coild have (1,6) (2,5)(3,4)(4,3)(5,2)(6,1)

OpenStudy (anonymous):

ohh so it's 6/36=.167 thank you so much!

OpenStudy (anonymous):

i dont think so

OpenStudy (anonymous):

6/36 is the probability if get a sum of 7

OpenStudy (anonymous):

but the probability of get a sum of 7 in the firts and a sum of 7 on the second is (6/36)*(6/36) given that they r independent events
