A single coin is tossed 300 times. Heads were observed 180 times. What is the long-run relative frequency of tails. Epress the answer in decimal form.
The total number of tosses is 300. The frequency of heads observed is 180.
Therefore, the frequency of tails observed is 300 - 180 = 120.
The long-run relative frequency of tails can be calculated as:
Frequency of tails / Total number of tosses
= 120 / 300
= 0.4
So, the long-run relative frequency of tails is 0.4.
