Final answer:
In Eric's experiment, the coin landed on heads 26 times and on tails 13 times, resulting in a ratio of heads to tails of 26:13, which simplifies to 2:1.
Step-by-step explanation:
In the probability experiment conducted by Eric, where he flipped a coin 39 times and the coin landed on heads 26 times, we can find the ratio of heads to tails. Since there were 39 flips in total and the coin landed on heads 26 times, it landed on tails 39 - 26 = 13 times. To find the ratio of heads to tails, we simply compare the number of heads to the number of tails.
The ratio of heads to tails is therefore 26 heads to 13 tails, which can also be simplified. To simplify the ratio, we divide both numbers by the greatest common divisor of 26 and 13, which is 13. So the simplified ratio of heads to tails is 2:1.
