.20 x 250 = 50
<u>Given</u>:
Sammy can paint the house by himself in 15 hours. With Nolan's help, it only takes 9 hours.
We need to determine the time it would take for Nolan to paint the house by himself.
<u>Time taken by Nolan:</u>
Let the rate that Sammy can paint the house by himself is 
The rate that Sammy and Nolan together paint the house is 
To determine the rate that it takes for Nolan to paint the house by himself is to subtract the rates.
Thus, we have;
Thus, the rate that it would take Nolan to paint the house by himself is 
The time that it takes for Nolan to paint the house by himself can be determined using the formula,
Substituting the values, we have;
Thus, Nolan takes 22.5 hours to paint the house by himself.

Answer:</h3>
1/17 or 0.0588 (without replacement)
<h3>
Step-by-step explanation:</h3>
To answer this question we need to know the following about a deck of cards
- A deck of cards contains 4 of each card (4 Aces, 4 Kings, 4 Queens, etc.)
- Also there are 4 suits (Clubs, Hearts, Diamonds, and Spades).
- Additionally, there are 13 cards in each suit (Clubs/Spades are black, Hearts/Diamonds are red)
.
In this case, we are required to determine the probability of choosing two diamonds.
- There are 13 diamonds in the deck.
- Assuming, the cards were chosen without replacement;
P(Both cards are diamonds) = P(first card is diamond) × P(second card is diamond)
P(First card is diamond) = 13/52
If there was no replacement, then after picking the first diamond card, there are 12 diamond cards remaining and a total of 51 cards remaining in the deck.
Therefore;
P(Second card is diamond) = 12/51
Thus;
P(Both cards are diamonds) = 13/52 × 12/51
= 156/2652
= 1/17 or 0.0588
Hence, the probability of choosing two diamonds at random (without replacement) is 1/17 or 0.0588.
