Explanation:
Given:
A fair coin
Required
Determine
![P(Head)](https://img.qammunity.org/2021/formulas/mathematics/college/6l4mutnpa455e1g8zt8k3cmkrjirv0337g.png)
A coin has two faces (Head (1) and Tail (1) )
i.e. 1 head and 1 tail
Both of which have equal probability, which is calculated as follows:
![P(Head) = P(Tail) = (1)/(1 + 1)](https://img.qammunity.org/2021/formulas/mathematics/high-school/tca80q4a5y693hs8tjcxy72t2yqd4p1d2o.png)
![P(Head) = P(Tail) = (1)/(2)](https://img.qammunity.org/2021/formulas/mathematics/high-school/2oni28tha6vu9rfk1sdtb80eejrr1n1r9x.png)
![P(Head) = P(Tail) = 0.5](https://img.qammunity.org/2021/formulas/mathematics/high-school/chixgthgqmcw6dxcz5jdtxe4pq7jp43d5j.png)
Hence:
![P(Head) =0.50](https://img.qammunity.org/2021/formulas/mathematics/high-school/8ym5jan7dqcdyaeic2lzexazqheno0i7lu.png)
