Answer:

it's 1/7^2

Step-by-step explanation:

When multiply bases with exponents, as long as they are the like bases, you add the exponents. 7^3 x 7^-5 = 7^-2.

When you have a negative exponent, you can get rid of it by moving it to a fraction. put a 1 over the base and exponent and drop the negative, so 1/7^2

The ______________ probability of an outcome is obtained by dividing the frequency of occurrence of an event by the number of tr

Norma-Jean [14]

Answer:

Empirical probability

Step-by-step explanation:

Empirical probability is data collected from experiment and real-life situation.

The "empirical probability" of an outcome is obtained by dividing the frequency of occurrence of an event by the number of trails of the experiment.

$\Longrightarrow: \sf{P(E)=\dfrac{\text{number of times event occured}}{\text{number of trails}}$

<u>Therefore, the correct answer is empirical probability.</u>
