Question

1. the math teachers at miller intermediate made an experiment to determine how many delta math lesson students were completing in both the 7th and 8th grade. the results of their experiment are in shown in the table.

	0-20	21-30	more than 30
8th grade	25	45	30

based on the results, what is the experimental probability that a student is in the 7th grade and completed more than 30 delta math lessons?
type a response.

Explanation:

Step1: Calculate total number of students

First, sum all values in the table:
$15 + 25 + 60 + 25 + 45 + 30 = 200$

Step2: Identify target group count

Find the number of 7th graders who completed more than 30 lessons:
$60$

Step3: Compute experimental probability

Divide target count by total student count:
$\text{Probability} = \frac{60}{200} = \frac{3}{10}$

Answer:

$\frac{3}{10}$ or $0.3$
