You flip 2 coins. what is the probability that one coin will land on heads and one coin will land on tails? createa sample space of outcomes.

HH, TT, HT, TH

2/4=1/2=50%

You have two coins. You want one to have tails, and one to have heads. This is a 50% (1/2) chance for either heads or tails on ONE coin. However, if you want the order you are asked, you have a 1/2 chance that one lands on head and one lands of tail. The reason is this:

There is only 4 different ways it would be resulted:

T = Tails

H = heads

H H, T H, H T or T T

Only T H and H T out of the 4 is valid, therefore 1/2 chance.
