Answer:
same lol
Step-by-step explanation:
Answer:
1). Rational
2). Irrational
3). Rational
4). Rational
5). Irrational
Step-by-step explanation:
To solve this question we should follow the rule,
"Addition of rational and an irrational number is an irrational number."
1). (rational number)
(negative rational number)
[rational number]
2). π → (Irrational number)
24 → (rational number)
π + 24 → (Irrational number)
Since addition of a rational and an irrational number is an irrational number.
3). = 2 (rational number)
5 (rational number)
2 + 5 = 7 (rational number)
4). (rational number)
(rational number)
(rational number)
5). (rational number)
→ (Irrational number)
→ (Irrational number)
Answer:
Probability to draw a club and second card is red without replacement will be or 12.75%
Step-by-step explanation:
A standard deck of cards contains number of cards = 52
And a standard deck contains number of club = 13
Now the probability of first card to be a club will be
=
Now this card is separated from the deck.
Therefore, number of remaining cards = 52 - 1 = 51
Second card has been drawn from the deck without replacement.
Since number of red cards in the deck = 13 + 13 = 26
Probability of the second card drawn =
Now probability that the first card is a club and the second card is red =
=
Or %
Therefore, probability to draw a club and second card is red without replacement will be or 12.75%
4a² − 20a + 25. is the answer.
