A single coin is tossed 300 times. Heads were observed 180 times. What is the long-run relative frequency of tails? Express the answer in decimal form.

1 answer

To find the long-run relative frequency of tails, we can use the formula:

Relative frequency = Number of tails / Total number of tosses

Since we know that the coin was tossed 300 times and heads were observed 180 times, we can calculate the number of tails:

Number of tails = Total number of tosses - Number of heads
Number of tails = 300 - 180
Number of tails = 120

Now we can plug these values into the formula:

Relative frequency = 120 / 300
Relative frequency = 0.4

Therefore, the long-run relative frequency of tails is 0.4.
