A fair coin is tossed twice, what is the probability of getting at least one head?*1/2

Sure, here is the step by step solution:

Step 1: Identify the total number of outcomes When a coin is tossed twice, there are 4 possible outcomes: HH, HT, TH, TT.

Step 2: Identify the favorable outcomes The favorable outcomes for getting at least one head are: HH, HT, TH.

Step 3: Calculate the probability The probability of an event is given by the ratio of the number of favorable outcomes to the total number of outcomes.

So, the probability of getting at least one head when a fair coin is tossed twice is 3/4 or 0.75.
