Final answer:
Galina's first box would contain 16 pieces of paper, as there are 16 possible outcomes from flipping a coin 4 times, with each flip doubling the number of outcomes.
Step-by-step explanation:
To determine how many pieces of paper were in the first box with all possible outcomes from flipping a coin 4 times, we must calculate the total number of outcomes. When flipping a coin once, there are two possible outcomes: heads (H) or tails (T). For each flip of the coin, the number of outcomes doubles since each outcome can lead to either an H or T on the next flip.
For one flip: 2 outcomes (H, T)
For two flips: 2 × 2 = 4 outcomes (HH, HT, TH, TT)
For three flips: 2 × 2 × 2 = 8 outcomes
For four flips: 2 × 2 × 2 × 2 = 16 outcomes
Therefore, the first box would contain 16 pieces of paper, with each piece representing one of the possible outcomes from flipping a coin 4 times.
