Answer: B.
Step-by-step explanation:
Hello!
If you drop a coin, it will either display one side of it or the second side of it.
This means it is a 50-50% chance to display the first or second side.
So, you have a 50% to get one side, but how about 2 coins?
Every coin will have a 50% chance, which means 1/2.
1/2 = 0.5
Multiply 0.5, by 0.5 because they are two coins. If were 4 coins, you would've got 0.5 to the power of 4 (4 coins).
0.5 * 0.5 = 0.25
0.25 = 0.25 / 1
Multiply this number by 100, to get the actual percentage.
25 / 100
Now, divide the fraction by 25, to get ireductible.
The answer is 1/4 , B.
