Question

Let x denote the sum of two distinct numbers selected randomly from the set of numbers StartSet 1 comma 2 comma 3 comma 4 comma 5 EndSet . {1, 2, 3, 4, 5}. Construct the probability distribution for the random variable x.

Answer 1

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.
