A coin lands on heads 200 times
the relative frequency of heads is 0.4

The number of times coin thrown was 500.

Step-by-step explanation:

Relative\ frequency=\frac{Number\ of\ lands\ on\ heads}{Number\ of\ times\ coin\ thrown}

0.4=\frac{200}{x}

By cross multiplying we get:

0.4x=200

Dividing both sides by 0.4 we get:

x=500.
