# Does it mean “two successive tosses is the same” is same as “two successive tosses is either heads or tells”?

I got confusion !

Does it mean "two successive tosses is the same" is same as "two successive tosses is either heads or tells" ?

I have two problems :

Q. I have an unbiased coin , assuming that the trials are independent, find the the expected number of tosses ? when unbiased coin is tossed repeatedly until the outcome of two successive tosses is____ .

1. Same

I have try to solve problems , I applied same logic .that's fine . answer will be Q.(2) 6 {e=2$^N$$^+$$^1$−2}but for Q.(1) 6(tells)+6(heads) = 12 times ?{but this question appear on a competitive and answer gives 3 } Please do not give "down vote" , This is not homework question ,I found from defferent -2 sources . Is it right , same = (heads +tells)/2 ? I need explanation for both .
