Find the mean for the set of data.<br> 0.2, 0.21, 0.17, 3.22, 0.2

Sholpan [36]

Answer:

0.8

Step-by-step explanation:

Find the mean of the list:

(0.2, 0.21, 0.17, 3.22, 0.2)

The mean of a list of numbers is given by:

(sum of elements)/(number of elements)

(sum of elements) = 0.2 + 0.21 + 0.17 + 3.22 + 0.2:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/(number of elements)

Counting, we see that the list has 5 elements:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5

0.2 + 0.21 + 0.17 + 3.22 + 0.2 = 4:

4/5

4/5 = 0.8:

уA 5-digit PIN number is selected. What it the probability that there are no repeated digits?hoThe probability that no numbers a

Ber [7]

Since there are 5 choices and there are 10 possible digits for each digit of the PIN( 0, 1, 2, 3, 4, 5, 6, 7, 8, 9)

The total value possible 5 pins are 10⁵ = 100000

Using permutation, since 5 numbers are selected without repetition:

$\frac{n!}{(n-k)!}=\frac{10!}{(10-5)!}=30240$

The probability that no numbers are repeated is= 30240/ 100000

≈ 0.302
