Answer: Choice C

The probability of getting all heads is the same as the probability of getting all tails

=========================================================

Explanation:

H = heads

T = tails

In the first row, we have HHH to signify three heads. This shows up 1 time out of 8 outcomes total (each row is a different outcome). The probability of getting HHH is 1/8.

In the last row, TTT means we got three tails. Like with HHH, it only shows up once out of eight times, so the probability of getting TTT is 1/8 as well.

Therefore, both HHH and TTT have the same probability. This is because both sides of the coin have equal chances to land on. If the coin was more biased toward heads for example, then HHH and TTT would have different probabilities.

Write an expression for the calculation add 3 and 8 and then multiply by 9
melisa1 [442]

Hey there!

Basically it wants you to add 3 and 8 from each other, what ever the answer to that part, you multiply the result by 9

Here this is what i meant

3 + 8 = 11 \\ 11 ( 9) = 99

Or you could do this method too!

(3 +8) (9) \\ \\ 3 + 8 = 11 \\ 11(9) \\ = 99

They both give you the result of 99

So, I am assuming your expression would look like this: (3 + 8) * 9

Good luck on your assignment and enjoy your day!
