Answer:

Step-by-step explanation:

Hey there!

A. 3x5 is 15! However since one of the number is a negetive, we must add a negetive sign to the 15, making it -15!

Remember this: A negetive number times a negetive number is a posititve number, but a negetive number times a positive number is a negetive!

B. 5+-5 is equal to 0, so 3x0 is 0!

C. No matter which way you mutliply it, whether it's -5x3 or 3x-5, the answer will always be -15! (-5)x(3+-3) is: 3+ -3 is 0, so -5 times 0 is the same thing as 5x0, which is still 0!

D. Like I said before, a negetive times a negetive is a positive, so -3x-5 is the same as saying 3x5, which is 15!

I hope this explanation helps you! Please mark me Brainliest!

The chance that a person is left handed is 0.15 or 15%. if you randomly select 8 people, what is the probability that they are a
Wittaler [7]
Answer: The probability that all 8 people are right handed is about 27.25%.

If the chance a person is left handed, the chance a person is right handed is 85%.

Now, we just need to find the chance that this 85% event happens 8 times in a row.

Simply, multiply it by itself 8 times.

(0.85)^8 = 0.2725

There is a 27.25% chance all 8 people are right handed.
