I throw a fair coin some number of times and the relative frequency of Heads is 0.45.1 throw the coin a few more times and the relative frequency is now equal to the theoretical

probability.

What is the minimum number of times the coin was thrown?

Its equal to d=7.07in

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
