Your question is Conditional Coin Probability. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
If you flip a coin twice and the first time it is head, what is the probability that the second time is also head?
Assume the coin is fair and the two flips are independent. State the conditional-probability calculation and explain why observing the first flip does or does not change the result.
