By using the trial method we get a total number of trials taken by Charlie to see both sides of both the coins is 4.
<h3>What is probability?</h3>
Probability is the name of the area of mathematics that deals with the examination of random events. The ratio of favorable occurrences to the total number of events is used to calculate an event's probability.
P(E) = F(E)/T (E)P(E)
It stands for the probability that an event will occur.
F(E) = Amount of favorable occurrences
Total number of trials (T(E))
Given that Charlie has 2 fair coins.
If he tosses the pair of coins simultaneously, then the number of samples can be HH, HT, TH, TT.
So to see both sides of both the coins he should toss the coin four times.

Hello this is how you do it!<3
9/4 = 21/4 therefore, 9/4 = 21/4
24/10 try to reduce the numerator and denominator by a common denominator 24/10 divided 2/2 = 12/5
16/2 divided 2/2 = 8/1 = 8
I hoped that help!<3
