A group of students tosses a fair coin 120 times and records the outcomes. If they observe that the coin lands on heads 70 times, what is the experimental probability of landing on heads?

1/2
1/70
7/12
2/3

The experimental probability of landing on heads can be calculated by dividing the number of times heads was observed by the total number of coin tosses.

Experimental probability of landing on heads = Number of heads observed / Total number of coin tosses
Experimental probability of landing on heads = 70 / 120
Experimental probability of landing on heads = 7/12

Therefore, the experimental probability of landing on heads is 7/12.
