One pen is chosen without looking from a bag that has 3 blue pens, 6 red pens, and 3 green pens.
sp2606 [1]

The probability of choosing. a green pen is 0.25

<h3>What is probability?</h3>

Probability is the likelihood or chance that an  event will occur. Mathematically;

Probability = Expected/Total outcome

If a bag has 3 blue pens, 6 red pens, and 3 green pens, then;

Total pen = 3+6+3

Total pen = 12

If a green pen is chosen, then

Pr(choosing a green pen) = 3/12

Pr(choosing a green pen) = 0.25

Hence the probability of choosing. a green pen is 0.25

Novosadov [1.4K]

9514 1404 393

Answer:

  D, 60 miles

Step-by-step explanation:

Distance is indicated by the vertical scale. The section that represents the most distance will be the section that has the greatest vertical difference between its start and end points. Section D starts at 60 and ends at 0 miles, so covers a distance of 60 miles. The greatest distance covered by any other section is 30 miles.

The person traveled the farthest during section D. They traveled 60 miles.

PLEASE PLEASE ANSWER FAST. there are 2 types of probability. one is called theoretical and the other has two names, they are wha
jonny [76]

Answer:

Actual probability or experimental probability is the name of the "other" type of probability. We can always calculate in theory how an event will go: if you flip a coin twice, you should get one head and one tail. Yet in actuality, if you run an experiment you won't always get that theoretical result.
