A fair coin is tossed 3 times. find the probability of getting at least 1 head.

Cool! So a coin has 2 sides, so therefore there is only a 50/50 chance. So 1/2 probability for getting heads on one coin toss. I do not know how to insert a probability tree but they are helpful! So 3 tosses, and if there’s only 2 possible outcomes for 1 toss, 2*3 which equals 6! 2 possible outcomes * 3 tries will give you the total possible outcomes. So you only need to land 1 head, so 3(possible heads)/6(total possible outcomes). Your answer is 3/6, or 1/2 simplified.

Ask google i believe they can you with that question
