Answer:
Step-by-step explanation:
Given:
The set of numbers {1, 2, 3, 4, 5}
Affter that, we find the sum um of two distinct numbers selected randomly from the set above;
- 1+2 =3
- 1+3=4
- 1+4=5
- 1+5=6
- 2+3=5
- 2+4=6
- 2+5=7
- 3+4=7
- 3+5=8
- 4+5 = 9
Therefore, we have the following number: 3,4,5,6,5,6,7,7,8,9
so we have x = {3,4,5,6,5,6,7,7,8,9 }
now we find P(x) of each number, we have n(S) = 10
x 3 4 5 6 7 8 9
P(x) 1/10 1/10 1/10 2/10 2/10 2/10 1/10
Hope it will find you well.
