Answer to Question #91996 in Statistics and Probability for Jessel Joy Gorres

Question

. Determine the range (possible values) of the random variable. Wood panelling can be ordered in thickness of 1/8,
1/4, or 3/8 inch. The random variable is the total thickness of panelling in two orders.

Answer 1

Let's go through all the possible options and find the unique formula

t₁+t₂=t;

t₁ is the thickness of the first panel;

t₂ is the thickness of the second panel;

t is the total thickness;

1/8+1/8=1/4;

1/8+1/4=3/8;

1/8+3/8=1/2;

1/4+1/8=3/8

1/4+1/4=1/2

1/4+3/8=5/8

3/8+1/8=1/2;

3/8+1/4=5/8;

3/8+3/8=3/4;

unique variants: 1/4; 3/8; 1/2; 5/8; 3/4 inch.

 Answer: 1/4; 3/8; 1/2; 5/8; 3/4 inch.
