What is a theoretical and Experimental Probability?
aniked [119]

Answer:

See below...

Step-by-step explanation:

Theoretical probability is the probability that something should happen based on the beginning conditions.  Such as having a jar of 30 marbles with 5 being blue.  The probability of pulling out a blue marble when selecting 1 marble is

5/30, or 1/6.  Theoretically you should pull one blue marble out every 6 times you pull a marble out.  

This isn't guaranteed to happen though, that's where experimental probability comes form.

Experimental probability is the number of desired outcomes achieved, divided by the total number of outcomes.  This is based on what actually happened.  Say you selected a marble, and put it back 10 times, recording the color each time and you got 2 blue marbles.  Your experimental probability is

2/10, or 1/5, which doesn't match the theoretical probability.  The more times this experiment is conducted, the closer your result will be to the theoretical probability

Mr. Rives' rotating sprinkler waters his lawn up to a radius of 7 feet. What is the maximum number of square feet of lawn mr. Ri
zaharov [31]

Answer:

Step-by-step explanation:

Mr. Rives' rotating sprinkler waters his lawn up to a radius of 7 feet. The formula for determining the area of a circle is expressed as

Area = πr²

Where

π is a constant whose value is 3.14.

r represents the radius if the circle.

The area covered by one of Mr. Rives' rotating sprinkler would be

3.14 × 7² = 3.14 × 49 = 153.86ft²

Therefore, the maximum area of lawn that two sprinklers can cover would be

153.86 × 2 = 307.72 ft²
