An upper-layer packet is split into 5 frames, each of which has an 90% chance
of arriving undamaged. If no error control is done by the data link protocol,
how many times must the message be sent on average to get the entire thing through?

i am not getting your point
"Intuitively speaking, the probability of getting a head is 1212 then how many attempts would get you a head (provided once tail has come it wont appear again)?"
what does is mean that no error handling is done by DLL aand what about remaining 10%
