Suppose that a large pumpkin empty a swimming pool in 40 hours and that a small pumpkin empty a pool and 70 hours working togeth
Norma-Jean [14]

Answer:

Total 25.45 hours will be taken to empty the pool.

Step-by-step explanation:

Time taken by large pumpkin to empty the pool=40 hours

Time taken by the smaller pumpkins to empty the pool=70 hours

Amount of pool emptied by large pumpkin in one hour=\frac{1}{40}

Amount of pool emptied by small pumpkin in one hour=\frac{1}{70}

Amount of pool emptied in one hour if both pumpkins work together=

\frac{1}{40}+ \frac{1}{70}

=\frac{11}{280}

Therefore, the no. of days will be the reciprocal of the amount of work done in one hour ie . \frac{280}{11}

Total 25.45 hours will be taken to empty the pool.

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
