Probability of rolling a 1 = 1/6
Probability of rolling a 1 = 1/6

Multiply these together (1/6)x(1/6) to get your probability that this will occur twice in a row.

(1/6)X(1/6)=0.02777777778 (the 7 is repeating)

This rounds up to 2.8% chance, or 2.78% (depends on what decimal place you have to round it to)

Answer:

  • Calculus texts: 600
  • History texts: 0
  • Marketing texts: 0

Step-by-step explanation:

Each Calculus text returns $10/2 = $5 per unit of shelf space. For History and Marketing texts, the respective numbers are $4/1 = $4 per unit, and $8/4 = $2 per unit. Using 1200 units of shelf space for 600 Calculus texts returns ...

  $5/unit × 1200 units = $6000 . . . profit

Any other use of units of shelf space will reduce profit.

Hello There!

Dividing a fraction is the same thing as multiplying by its reciprocal.

This means that \frac{3}{4} ÷ \frac{5}{12} is the same as multiplying \frac{3}{4} by \frac{12}{5}.

So basically when you divide you leave the first fraction alone but the second fraction in this case, 5/12 you would flip the number on top and the number on bottom to 12/5.

HAVE A GREAT DAY!
