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:

$\begin{gathered} p=\frac{1}{16}\cdot\frac{1}{15}\cdot\frac{1}{14}\cdot\frac{1}{13} \\ p=\frac{1}{43680} \end{gathered}$

What’s the median of 28,45,12,34,36,45,19,20

Ipatiy [6.2K]

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.
