ANSWER:
The probability is 1/43680
STEP-BY-STEP EXPLANATION:
We have the following:
0. The probability that Morgan is chosen first = 1/16. Now there are 15 students left after this.
,
1. The probability that Harmony is chosen second = 1/15. Now there are 14 students left after this.
,
2. The probability that Kenny is chosen third = 1/14. Now there are 13 students left after this.
,
3. The probability that Ben is chosen fourth = 1/13.
Therefore, the required probability is:
36 erasers shared in the ratio 6 is 6 (36/6)
So the is 6 in 1 ratio.
6 x the ratio 2 is 12
So there are 12 pencils
Answer:
Median = 31
Step-by-step explanation:
The median is the middle number which comes after arranging the set in ascending order.
Here, the given data is: 28, 45, 12, 34, 36, 45, 19, 20
The data arranged in the ascending order is as follows:
12, 19, 20, 28, 34, 36, 45, 45
Since the number of terms is even, we have two middle numbers, viz.,
28 and 34
The median would be the average of these two.
Therefore, Median = 28+34/2
= 31
The answer is 31.
