Question 1119888: Please help me solve this of simple way. Thank. You
Three coins are tossed. Find the probability of tossing each of the following events:
1. Three heads.
Answer:
2. Two heads and a tail.
Answer:
3. At least one tail.
Answer:
4. At least two heads.
Answer: Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! Three heads is (1/2)(1/2)(1/2) or 1/8
Two heads and a tail can occur 3 different ways, HHT HTH THH, so its probability is 3/8.
At least one tail is 1-no tails, which is 1-(1/8)=7/8
At least two heads is two heads (3/8 probability from above) and three heads, which is probability 1/8. The sum is 1/2.
