Question

A spinner is divided into ten equal segments. Each segment is numbered one through nine and one segment is labeled with "Free Spin." Isaiah spins the spinner ten times and gets a number eight times. What is the probability that he will get a number on the eleventh try?

zero percent

ten percent

ninety percent

one hundred percent

Answer 1

I don't even think the first ten spins are relevant here. @saifoo.khan ?

Answer 2

It's not like the first ten spins influence the eleventh...

Answer 3

ikr

Answer 4

Well, then, ignoring the apparently irrelevant fact that this is the eleventh spin, if you spin the wheel, what are the chances that you get a number?

Answer 5

so its 10%

Answer 6

would it be 90% ?? Because the chances of getting a number on a spin is 9/10. I don't think the number of spins matters. Maybe I am wrong, or maybe I am right. You will need a second opinion. (9/10 = 90% )

Answer 7

I think I would be

Answer 8

Yeah, that :D

Answer 9

Answer 69

Darien has raw data that shows how many hot sandwiches, cold sandwiches, wraps, and salads he sold in his sandwich shop in one day. He wants to compare the number of large and small of each type of meal he sold during the day. Should he use a bar graph, a double bar graph, or a circle graph? Explain.

Answer 70

I think it is the double bar graph. He is comparing the large and small of each type of meal. Take a look at a double bar graph and see what you think.
