Question

Which set of data shows fifty percent as the experimental probability of a particular traffic light being green on your way to school in the morning?

ten of twenty-five selections at random from a card deck being a black card, with black representing a green light

2 tails in twenty coin flips, with tails representing a green light

2 odd-numbers in 8 rolls of a standard die, with odd numbers representing a green light

spinning twenty vowels out of forty spins of a spinner with 6 equally divided sections labeled with 3 vowels and 3 consonants

Answer 3

Assumption: the traffic light shows green or red. (There is no yellow in this experiement.)

Option1: ten of twenty-five selections at random from a card deck being a black card, with black representing a green light

Empirical Probability of Green is 10/25 which is not 1/2 or 50%.

Option2: 2 tails in twenty coin flips, with tails representing a green light

Empirical probability of green is 2/20 is not 1/2.

Option3: 2 odd-numbers in 8 rolls of a standard die, with odd numbers representing a green light

Empirical probability of green is 2/8 which is not 1/2

I leave the analysis of Option4 to @TurtleNadz along with a comment that whoever created this question needs a lesson in writing with clarity.

And, I cannot certify that the answer that will result is correct given the way the problem is written.

Let me know how it turns out, okay?
