1/21x = 1/7
x = 1/7 * 21
x = 21/7
x = 3 <===

<h2>
<em>ANSWER </em><em>BELOW:</em><em>-</em></h2>
Step-by-step explanation:
Theoretical probability describes how likely an event is to occur. We know that a coin is equally likely to land heads or tails, so the theoretical probability of getting heads is 1/2. Experimental probability describes how frequently an event actually occurred in an experiment.
EXAMPLE-
Theoretical probability:
For instance, since a flipped coin has two sides and each side is equally likely to land up, the theoretical probability of landing heads (or tails) is exactly 1 out of 2.
Experimental probability:-
For example, the probability of getting a head if you flip a coin is ½, since only 2 things could happen (a head or a tail) and each one has an equal chance of occurring.
