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.
Answer:
3

37 is an rational, whole and intenger number
Answer:
x= -3
Step-by-step explanation:
Solve the rational equation by combining expressions and isolating the variable x.
Answer:
90
Step-by-step explanation:
Divide the larger number by the smaller. Obtain the quotient and remainder.
If remainder is zero then smaller number is the GCF
If not then repeat the process with the remainder and smaller number until a remainder of 0 is reached.
= 1 remainder 90, then
= 1 remainder 0
Hence GCF is 90
90 = 2 × 3 × 3 × 5 =
