50%.

there is only 2 possibilities (head or tails), since the first coin is already defined.

next.

33%
there are 3 options:
heads and heads
tails and heads
heads and tails
one of the 3 options is both on heads

100%

0%

The question is purposefully worded oddly to throw people off. Ask either "What is the probability that two coins that are flipped at the same time will land heads" OR "What is the probability that one coin will land heads". Don't mash up the questions into a convoluted shitty sentence.

25%

No

When you introduce 2 variables at 50% individually ,they become 25% as a pair

1/3

seems only three people understood the question

answer to the first is 25% which no one would say is the answer to the original question. Answer to the second is 50% but for a different reason than what is typically said for the original. Its not that convoluted just pretend someone flips two coins in front of you, doesnt let you see them and tells you atleast one is heads

Probability of event one being the first coin landing on head is 1/2. Probability of event two being the coin also landing on head is also 1/2. You can simply multiply the two events to find the probability of both kf them happening.

first of all you need to define or exclude landing on the edge.

if its an 2d object, so has no edge, the following has to be answered
1. because it has no weight and flipping it does not mean it goes down again.
2. if it hits a flat surface, there is not area it can cover so it goes throught that surface.

if you define a 2D weight, you still have the problem from (2.)
if you define a impermeable surface you can not calculate the movement after impact of 2D coin on surface as its 2D.

you should not play with money

If you flip two coins there are four options for how they land:
H H
T H
H T
T T
Seeing as there is at least one heads you can remove the last option. Only three options remain, of which one is two heads, so 1/3.

>never heard of conditional probability

You are a retard.

1/2 * 1/2 = 1/4 sooooooo 50% * 50% = 25%?
is me math right?

Imagine being this retarded

weird explanation but it is correct

what is the least coin? seriously, based on theory of relativity (and Im just a spectator here) the sequence of events is not clear here.
as Im not interacting but just spectating it could also be possible that this event is outside the for me accessible spacetime events and still is valid.

It's one or the other two, since the other two are the same result. Therefore it's 50-50.
As another user mentioned, it's strangely worded so idiots will argue on it.

by that logic landing two heads would be 1/3 because the 3 options are heads and heads, tails and heads and tails and tails. but obviously its 1/4 chance of landing two heads because two coin flips with each 1/2 chance of landing heads.
