Ummm, A?

Answer 4

No. You have half a chance of flipping heads and half of flipping tails.

Study the possible answers and what you know (or are supposed to know) about probability. You have one more chance to get it right here.

Answer 5

So, it has to be either B or C. Hmmm...

Answer 6

Yes.

I've checked them twice. Now you're on your own.

Hi, Ms. Sue, I'm Connor's mother. I was wondering if you can help with Connor by doing the problem shown above. My son is struggling on math, and he yet has autism. Honestly, he;s very intelligent in Language Arts and Science. Math is his weakest subjects. Thank you, good day.
