When a coin is tossed, the probability of getting the head is ______ and the probability of getting the tail is ______.

The probability of an event is given as:

Probability of an event = $\frac{\mathrm{Outcomes} \mathrm{of} \mathrm{an} \mathrm{event}}{\mathrm{Total} \mathrm{possible} \mathrm{outcomes}}$

When a coin is flipped, it has a total of 2 possible outcomes - Head and Tail.
Probability of getting a head = $\frac{1}{2}$
Probability of getting a tail = $\frac{1}{2}$

Therefore, ($\frac{1}{2}$) is the correct response.
