Question

You flip a coin 5 times and get H, H, H, H, H. What is the probability that you will get another H?

Answer 1

Answer:

Step-by-step explanation:

If you flip a coin once, you have a 1/2 chance of getting heads. You will get either a head or tail.

Flipping a coin twice gives you a 1/4 chance of getting 2 heads since you will either get a 2 heads, 2 tails, a tail then head, or a head then tails.

From this we can see its pretty likely the pattern will continue if our chances of continually getting a head keeps halfing. So we can represent it as 1/2^n (half to the power of n) where n is the number of times we flip the coin.

So the odds of flipping a coin 5 times and getting 5 heads are 1/2 ^5 (half to the power of 5). Which gives us 1/32 or just over a 3% chance.

Answer 2

Answer:

1/2

Step-by-step explanation:

When we flip the coin, there are only two possibilities. Either H or T comes. So the probability of getting one more H will be 1/2
