What is the probability of flipping 3 coins on the same side, that is getting either all heads or all tails? Give the exact decimal answer without rounding.

When flipping 3 coins, each coin has 2 possible outcomes: heads (H) or tails (T). The total number of possible outcomes when flipping 3 coins is:

\[
2^3 = 8
\]

These outcomes are:
- HHH
- HHT
- HTH
- HTT
- THH
- THT
- TTH
- TTT

Among these 8 outcomes, the outcomes where all coins are on the same side are:
- HHH
- TTT

There are 2 such favorable outcomes.

Thus, the probability \( P \) of getting all three coins on the same side is the number of favorable outcomes divided by the total number of outcomes:

\[
P = \frac{2}{8} = 0.25
\]

So, the exact decimal answer is \( 0.25 \).
