PLEASE HELP FAST I NEED THIS QUICKLY

One dozen students each drop a brass tack six times from a height of six inches onto a level hard surface. They record the number of times the tack lands point up. The table below lists their results.

Answer:

0.833

Explanation:

1. locate which vertical column of the graph we are referring to:

  • student 7

2. calculate the total number of trials student 7 did:

  • if in 5 trials the tack landed point-up, and in 1 trial the tack did not land point-up, the total number of trials is 6
  • 5 + 1 = 6

3. refer back to the question:

  • the question states: "what is the experimental probability that the tack lands point-up"

4. interpret the graph:

  • of the 6 trials student 7 underwent, the graph tells us that 5 landed point-up.
  • therefore the experimental probability of a tack landing point up is 5/6 (in 5 out of the 6 trials, the tack landed point-up)

5. converting from fraction to decimal:

  • all the given answers are given in decimal form, whilst our current answer (5/6) is in fraction form.
  • to convert to decimal form, simply divide the top number by the bottom number
  • 5 ÷ 6 = 0.833

therefore, the experimental probability that the tack will land point-up, is 0.833

hope this helps :)
