Answer:
1/2 or 50%
Explanation:
The probability of an event occurring is the number of ways the event can occur divided by the total number of possible outcomes.
In the case of tossing a coin, there are two possible outcomes: heads or tails. If you toss a nickel, the probability that "heads" will come up is 1/2, or 50%. This is because there is only 1 way for heads to come up (by getting heads) and 2 total possible outcomes (heads or tails).
Therefore, the probability that "heads" will come up when you toss a nickel is 1/2, or 50%.
