A locker requires a three-digit code to open the lock. The code must contain one letter and two numbers, and no letter or number can be repeated. You can choose from among four letters, A, B, C, and D, and two numbers, 5 and 6.

The size of the sample space is: (8, 16, 20, 24)

If a code is chosen at random, the probability that it has a letter that immediately follows an odd number is: (1/8, 1/6, 1/3, 2/5, 2/3)

If a code is chosen at random, the probability that D is in the code but is not in the first position is: (1/8, 1/6, 1/3, 2/5, 2/3)

Answer:

The probability that a customer purchases a black SUV is 0.05.

Step-by-step explanation:

The question is incomplete:

At a certain car dealership, the probability that a customer purchases an SUV is 0.20. Given that a customer purchases an SUV, the probability that it is black is 0.25.

The probability that a customer purchases a black SUV can be calculated as the multiplication of this 2 factors:

The probability of a customer purchasing a SUV: P(SUV).
The probability that it is black, given that he or she purchases a SUV (conditional probabilty): P(B|SUV)

We know then:

$P(SUV)=0.25\\\\P(B | SUV)=0.20$

We can now calculate the probability as:

$P(B\,\&\,SUV)=P(B|SUV)\cdot P(SUV)=0.25\cdot0.20=0.05$
