Now
68 can be written as
68 = 2 * 2 * 17
The given is

It can be written as

=
Now
=
.
so given become

∵√2² = 2
∵a*√b=a√b

Answer:
Die: 16. 2/3%
Coin: 50%
Step-by-step explanation:
Well rolling a 4 on a 6 sided die is 1/6.
To make that a percent we first make it a decimal.
1 ÷ 6 = .16666 repeating
To make this a percent we move the decimal place 2 times to the right.
16.2/3%
The chance of flipping a heads on a fair sided coin is 50% because there are two sides with a 50/50 chance of being either.
<em>Thus,</em>
<em>for rolling a 4 on a 6 sided die there is a 16.2/3% chance and a 50% for flipping a heads on a 2 sided coin.</em>
