# What is the Probability of Head in coin flip when coin is flipped two times if coin is biased (\$60%\$ chance of heads per flip)?

If unbiased coin then the probability of Head in coin flip when coin is flipped two times $$= 75%$$.
$$P(H_1 cup H_2) = frac12 + frac12 − frac12 times frac12 = frac34$$

But what is the probability of Head in coin flip when coin is flipped two times if the coin is biased and has a $$60%$$ chance of heads rather than $$50%$$?
