leva [86]

Answer: Option B

Step-by-step explanation:

First we assign a name to the events:

Event S: a customer buys socks

Event H: a customer buys shoes.

We know that :

$P (S) = 0.15$

We also know that the probability of S given that H occurs is:

$P(S|H) =\frac{P(S\ and\ H)}{P(H)}=0.20$

If two events S and H are independent then:

$P (S) * P (H) = P (S\ and\ H)$

This mean that if two events S and H are independent then:

$P(S|H) =\frac{P(S)*P(H))}{P(H)}$

$P(S|H) =P(S)$

We know that:

$P(S|H) =0.20$ and $P (S) = 0.15$

$0.20\neq 0.15$

This means that S and H events are dependent.

The answer is the option B

Aleks [24]

Answer: Relative error = 50%

Step-by-step explanation:

Relative error Re = Absolute error/True value × 100%

True value = 2 scoops

Measured(used) value = 3 scoops

Absolute error Ae = measured(used) value - True value

= 3 scoops - 2 scoops

Ae = 1 scoop

Re = 1/2 × 100%

Re = 50%
