If you toss a coin three times, what are the odds against getting exactly three heads?

i believe there is a 50% chance of getting a toss of more then 1 head in 3 tosses. if you look at a chart you will see that the possible outcomes are hhh, hht, hth, htt, thh, tht, tth and ttt. as you can see if you add up all the possible outcomes with more then 1 head you will get 4/8.

hope this : )
