You flip a coin twice. find the probability that at least one of the tosses showed heads.

1/2, 50%,

In one coin, there is one head and 1 tail

In 2 flips, there are 2 heads and 2 tails

So, all together, there are 4 different possibilities, and 2 are heads

hope this helps!

1/2 because 1 out of 2 is 1/2
