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.
A. The drop-out rate can be estimated using the equation,
d = my + b
where d is the drop-out rate, m is the slope of the line, y is the number of years from 1998 and b be the initial value. For 2008,
18.3 = m(2008 - 1998) + 38.46
The value of m from the equation is -1.12. The equation becomes,
d = -1.12y + 38.46
b. The vertical intercept of the model is when d is equal to zero.
0 = -1.12y + 38.46
The value of y from the equation is 34.34.
(34.34, 0)
c. n = 1990 + 34.34 = 2024.34.
The vertical intercept of this problem tells me that by the year 2024, the drop-out rate would be 0%.
