Observe the frequencies of the heads and tails from table 1, 2 and 3. Write down the total frequencies for heads and tails Table 4: Totals of Head and Tails

The problem requires data from a coin-flipping experiment for Day 1, Day 2, and Day 3. Since this data is not provided, we will use hypothetical results to demonstrate how to complete the tables and calculate the totals. The "Tallies" column would be filled with marks representing each flip, but for this demonstration, we will focus on the numerical frequencies.

Assuming 100 coin flips for Day 1, let's say we get 50 Heads and 50 Tails.

• Heads: Frequency = 50
• Tails: Frequency = 50
• Total: Frequency = 100

Assuming 100 coin flips for Day 2, let's say we get 45 Heads and 55 Tails.

• Heads: Frequency = 45
• Tails: Frequency = 55
• Total: Frequency = 100

Assuming 100 coin flips for Day 3, let's say we get 53 Heads and 47 Tails.

• Heads: Frequency = 53
• Tails: Frequency = 47
• Total: Frequency = 100

To find the total frequencies, sum the hypothetical frequencies from Day 1, Day 2, and Day 3.
Total Heads = $50 (\text{Day 1}) + 45 (\text{Day 2}) + 53 (\text{Day 3}) = 148$
Total Tails = $50 (\text{Day 1}) + 55 (\text{Day 2}) + 47 (\text{Day 3}) = 152$

The completed TABLE 4: Totals of Head and Tails is:

The total frequencies for heads and tails are:
Heads: $\boxed{\text{148}}$
Tails: $\boxed{\text{152}}$
