>>938059202 (OP)
Quarter and Dime
Possible results are
QT, DT
QT, DH
QH, DT
QH, DH
All are equal likely to happen
So the coins are flipped and a guy peeks at the result and doesn't say what it is, but says,
"It's one of these three:
QT, DH
QH, DT
QH, DH"
The odds both are heads is 1 in 3.

But it says they both need to be heads.
If it flips on a T, there's no guarantee it will be a H.
So, if we know for the condition to be true, one must be H.
The second can be T or H, so it's a 50% spread.
I think gamblers fall for this kind of logic. That TH "matters" in the probability array.
>>938059278 >Two coins are flipped.
Okay. >If at least one of the coins landed heads,
Lets assume this as an absolute number with the assertion that one coin will always be heads >what is the probability that both coins landed heads
You have to assume now that you are only flipping the second coin because the first one is always presumed to be heads.
50% makes sense.
