Answer:
3/20
Step-by-step explanation:
Total number of students = 15 + 10 = 25
Number of girls = 10
Number of ways to select 2 students =
Number of ways to select 2 girls =
Compute the probability of selecting two girls as follows:
Thus, the probability that both students are girls is 0.15.
0.15 simplified in fraction from: 3/20
The frequency refers to how many times a test scores within that particular range.
To find this answer, we must divide the number of scores we are interested in by the number of total scores, aka (n/500).
We are interested in the range of 70-89, and we notice there are 2 boxes included in this range: 70-79 and 80-89.
In the 70-79 range we see that there are 172 out of 500 scores.
In the 80-89 range we see that there are 105 out of 500 scores.
If you add these scores, you are given 277 out of 500 scores, aka (277/500), which gives us 0.554
You were on the right track with the answer you chose but you just forgot to include the 80-89 range. Hope this helps!
