Answer:
61/125 or 0.488
Step-by-step explanation:
Total = 5×5×5 = 125
Numbers with no 4 = 4×4×4 = 64
Atleast one 4= 125-64 = 61
P(atleast one 4) = 61/125 or 0.488
The answer would be better D.
Answer:
Ben expected to earn $27,675 this year.
Step-by-step explanation:
First, to be able to determine the difference between this year and last year, you would multiply $22,500 by 0.23 (or, 23% in decimal form).
When you do that, the answer comes out to 5,175.
So then, you add $22,500 and $5,175 in order to get the value that he expected to earn this year. That comes out to $27,675, which is your final answer.
