SOLUTION

Looking at this, we have a total of four prices.

When the first price is picked, the probability becomes

[tex]\frac{1}{4}[/tex]

After the first price is picked, we have 3 prices left. The probability of picking the second becomes

[tex]\frac{1}{3}[/tex]

Probability of picking the 3rd becomes

[tex]\frac{1}{2}[/tex]

Note that this is without replacement, hence the probability of picking the last becomes

[tex]\frac{1}{1}=1[/tex]

So the require probability becomes

[tex]\begin{gathered} \frac{1}{4}\times\frac{1}{3}\times\frac{1}{2}\times1 \\ =\frac{1}{24} \end{gathered}[/tex]

Hence the answer is

[tex]\frac{1}{24}[/tex]

It is a dependable probability because it is a probability without replacement, since the preceding event has an effect on the probability of the next event

Hence the answer is dependable probability
