Question

If you toss a coin, what is the probability of it landing tails up?

answer : 5 %
1/2 = 0.5 in % is 5
is that correct ?

Answer 1

There are only 2 possible outcomes: Heads, Tails.
Thus, the theoretical probability of Tails is 1/2, or 0.50, or 50%.

Answer 2

no because its 50% because its only got 2 sides

hope that helps
