Aspecial 8 sided die is rolled 20 times with these outcomes:

2, 4, 7, 3, 1,5, 4, 6, 3, 8, 6, 2, 5, 2, 6, 1, 7, 4, 5, 6

what is the experimental probability of rolling a 2 or a 4?

is this number great than or less than the theoretical probability of rolling a 2 or 4?

explain.

A. 30%

B. Higher

Step-by-step explanation:

A. What is the experimental probability of rolling a 2 or a 4?

Let's see how many 2s and 4s have been rolled.

Three 2s and three 4s have been rolled,

So, out of the 20 rolls, 6 were a 2 or 4.

That makes that the experimental probability to get a 2 or a 4 is 6 out of 20 rolls, so:

6/20 = 30%

The experimental probability is then of 30%, which is pretty high considering it's an 8-sided die, since it's almost at par with the theoretical probability of a 6-sided die.

B. Is this number great than or less than the theoretical probability of rolling a 2 or 4?  Explain.

It's higher.  The theoretical probability to get a 2 or 4 would be for it to land on 2 sides out of 8 sides, so 2/8 = 25%.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .
