<h2>Answer:</h2>
Option: D is the correct answer.
D. 0.45
<h2>Step-by-step explanation:</h2>The results of the experiment are given as follows:
Coin Experiment Side of Coin Number of Tosses
Heads 18
Tails 22
This means that total 40 experiments were performed.
( Since 18+22=40)
Also, the number of times head turn up=18
Hence, the experimental probability of getting heads is:
Ratio of number of times head turn up to the total number of experiments performed.
Hence,
Hence, the experimental probability of getting head is:
0.45
6 & 8
Now we will compare these
6 is less than 8
So, 6/12 is less than 8/12.
