how many different two digit numbers can you form using the digits 4,5,1,8, and 2 without repetition?

20

Explanation:

4, 5, 1,8 and 2.

If we count them we have 5 numbers.

Then we want to form two-digit numbers without repetition.

There are 5 numbers possible to occupy the first digit, 4, 5, 1, 8 and 2.

Because it’s without repetition, the number that filled the first digit cannot be the second digit.

So the number possible to occupy second place is 4 different numbers. (5-4)

So there are 5 x 4 = 20 numbers that can we form from those 5 numbers: 4, 5, 1,8 and 2 without repetition.

binomial distribution

median= 2

range = 7-0 = 7

how to find median?

no. of term=28

median=(28+1)/2=14.5th term

the 14th and 15th term are 2, therefore the median is (2+2)/2 = 2

- 70

this is the answer for you hope it
