Question

medal given, help please :)
Which of these is a member of the sample space

when you flip a coin twice and then roll a die?
A)1-Heads-1
B)3-Tails-5
C)Heads-Tails-3
D)Heads-Tails-7

Answer 1

if you only roll a die 1 time, how many number should you get out?

Answer 2

well if you roll a die once and it lands on one side you only get one number out of it

Answer 3

exactly! so since options A and B both have 2 numbers in them, they can't be possible!

Now you're down to options C and D. Only one of them is possible.. Do you notice anything incorrect with either of them?

Answer 4

I believe C is the correct answer i don't have a explanation on how but D just seems impossible heads-tails-7 i don't see where 7 comes into play when they flip a coin twice & roll a die

Answer 5

Its a bit silly of a question. The question wants you to assume that you are using a standard 6 sided die. Since it only has 6 sides, you can't possibly get a 7.

In other words, you're absolutely right!

Answer 6

i didn't even think of that way but i just knew it didn't make any sense because 7 wasn't even mention into the question.

Answer 7

if you want to think about it more visually, consider this table:

Everything in the table represents a part of the sample space.
The representative sample space would be if you picked one thing from each column of the table.
In other words, if you can't get one of the answer choices by circling one thing from each column, its not part of the sample space and can't be the answer!

Answer 8

Proof that C works

= Heads Tails 3
