Since we are doing flips of a coin, we can agree that each flip is independent of all of the other.

The probability that a coin lands on heads is 1/2, just as the probability that a coin lands on tails is 1/2.

Since each event is independent, we take the probabilities of the events and multiply them together to get the overall probability:

P(H) = 1/2
P(T) = 1/2

So:

P(H, T, H, H, H) = (1/2) x (1/2) x (1/2) x (1/2) x (1/2) = 1/32

The overall probability is 1/32.

The answer would be B.
the -6 means it would go left, and the 9 would mean go up.

What is the GCF of 15 and 30

Answers

The greatest common factor (GCF) of 15 and 30 is: 15

Factors of 15: 1, 3, 5, 15
Factors of 30: 1, 2, 3, 5, 6, 10, 15

The common factors between the two numbers are 1, 3, 5, and 15, but considering 15 is the highest number out of them all, it is the greatest common factor.

The greatest common factor of numbers 15 and 30 would be 15.

Given that,

The two numbers are 15 and 30.

Used the concept of the greatest common factor that states that,

The GCF is defined as the largest number that is a factor of two or more numbers.

For example, the GCF of 24 and 36 is 12, because the largest factor that is shared by 24 and 36 is 12.

Here, The two numbers are 15 and 30.

Now, the factors of 15 and 30 are,

Factors of 15: 1, 3, 5, 15

Factors of 30: 1, 2, 3, 5, 6, 10, 15

Clearly, the largest factor that is shared by 15 and 30 is 15.

Therefore, GCF (15, 30) = 15
