A single coin is tossed 500 times. Tails was observed 200 times. What is the long-run relative frequency of Heads? Decimal form

Do it like a 7th grader?

To find the long-run relative frequency of Heads, we can subtract the number of times Tails was observed from the total number of coin tosses, then divide by the total number of tosses.

Heads was observed 500 - 200 = 300 times.

So, the long-run relative frequency of Heads is 300/500 = 0.6.
