Module 6 Lesson 5: Data Observation
Henry tossed a coin several times and recorded the number of heads and tails in the following table:
Coin Experiment
Side of Coin Number of
Tosses
Heads 12
Tails 18
What is the experimental probability of getting heads?
(1 point)
Group of answer choices
0.4
0.7
1.2
1.8
To find the experimental probability of getting heads, we use the formula:
Experimental Probability = Number of successful outcomes / Total number of outcomes
In this case, the number of successful outcomes (getting heads) is 12 and the total number of outcomes is 12 (heads) + 18 (tails) = 30.
So, the experimental probability of getting heads is:
12 / 30 = 0.4
Therefore, the answer is:
0.4
