When you flip a coin, what is the probability that it will come up tails?
1
1/2
1/4
1/8

Since there are only 2 sides on a coin, head or tails, the maximum possibility (denominator) is a 2
The probability it will land on a head instead of tails is 1/2, the probability it will land on tails instead of head is 1/2
1/2 + 1/2 = 2/2 = 1
Therefore, the probability of one side being flipped is 1/2

The answer is b. 1/2

Since there are only two sides of a coin, and each side contain equal chances of landing, the probability to get tails is 1/2 or 50%.
