Oduvanchick [21]

Answer:

Step-by-step explanation:

Two cards are drawn from a standard deck without replacement. What is the probability that the first card is a spade and the sec
Verizon [17]

Answer:

The answer is 0.123.

Step-by-step explanation:

You want to find the intersection between P(Spade) and P(Red). Knowing that there's no replacement, the probability will be given by the formula:

⇒ P(Spade∩Red) = P(Spade)*P(Red/Spade)

⇒ P(Spade∩Red) = P(Red)*P(Spade/Red)

Either formula works, but I'm going to choose to work with the first formula.

Therefore:

P(Spade) = \frac{13}{52}

P(Red/Spade) =  \frac{26}{52-1}

So:

P(Spade∩Red) = \frac{13}{52}*\frac{26}{51}= \frac{13}{102} =  0.123
