Answer:
Step-by-step explanation:
There are three reasons here why randomization is not being applied.
First, the coach is only observing football players attending the meeting. This is not representative of the entire team.
Second, there is no selection process. The coach isn't using a random generator or using a similar method.
Third, the players are volunteering for the test. The results will be biased because of this.

Answer:
266.67
Step-by-step explanation:
120=.45(x)
x=266.67
Answer:
a)120
b)6.67%
Step-by-step explanation:
Given:
No. of digits given= 6
Digits given= 1,2,3,5,8,9
Number to be formed should be 3-digits, as we have to choose 3 digits from given 6-digits so the no. of combinations will be
6P3= 6!/3!
= 6*5*4*3*2*1/3*2*1
=6*5*4
=120
Now finding the probability that both the first digit and the last digit of the three-digit number are even numbers:
As the first and last digits can only be even
then the form of number can be
a)2n8 or
b)8n2
where n can be 1,3,5 or 9
4*2=8
so there can be 8 three-digit numbers with both the first digit and the last digit even numbers
And probability = 8/120
= 0.0667
=6.67%
The probability that both the first digit and the last digit of the three-digit number are even numbers is 6.67% !
