Answer:
2.41 and 2.50
Step-by-step explanation:
Here, we shall be selecting the correct answer from the option.
a. A is correct
the number we want is between 2.4 and 2.8
2.5 is greater than 2.4 but less than 2.5, this means it meets our criteria
b. 2.41 is also correct
This is because it is greater than 2.4 but less then 2.8

Answer is 7.5 pencils per dollar
Answer:
4/5
Step-by-step explanation:
Given that:
Number of options = a, b, c, d, e
Number of correct answer choice = 1
Therefore, number of wrong answers = 4
Recall :
Probability = (number required outcome / number of total possible outcomes)
P(wrong answer) :
Number of Required outcome = number of wrong answer choices = 4
Total answers = 5
Hence,
P(wrong answer) = 4 / 5 = 0.8
