Answer 1

Sarah used a probability simulator to roll a 12-sided number cube 100 times. Her results are shown in the table below:


Number on
the Cube Number of
Times Rolled
1
18
2
5
3
10
4
12
5
16
6
5
7
8
8
14
9
2
10
5
11
2
12
3


Using Sarah's simulation, what is the frequency of rolling a 2 on the number cube?
100 over 5
100 over 95
95 over 100
5 over 100

Answer 2

@phi

Answer 3

i think the only realistic answer is 5/100

Answer 4

are you sure its d?

Answer 5

yep only realistic answer

Answer 6

ok

Answer 7

frequency = number of times rolled / 100

Answer 8

d?

Answer 9

So the number of rolls displayed is 24...
of which, a 2 came up on 3 of those rolls.

Oh nevermind, I see what's going on.
Your table is broken :(
it's impossible to read this table.
Maybe paste a picture of it.

Answer 10

ok

Answer 11

The 5 is after the 2, so that's probably the one that went with it :d
ya Chris prolly has the right idea.
5 of the 100 rolls were 2's.
5 over 100.

Answer 15

These are `independent events`,
so the probability of BOTH happening will be the `product` of the probability of each.
