The total sum of students given four quarters = The student who spent the money on gum plus the students that kept the money.

34+17=51

The total sum of students given four quarters is 51 students.

The student who spent the money on gum is 34 students.

The probability of the students that spent the money, given that the students were given four quarters,

\frac{\text{The probability of students that spent the money}}{\text{The total sum of students given four quarters}}=\frac{34}{51}

The probability is,

\frac{34}{51}=\frac{2}{3}=0.66667\approx0.667(3\text{ decimal places)}

The probability is 0.667.

Form a sequence that has two arithmetic means between 13 and 88.
hichkok12 [17]

Answer:

Correct choice is A

Step-by-step explanation:

For the numbers 13 and 88, find the difference 88-13:

since 88-13=75 and \dfrac{75}{3}=25 (two arithmetic means tells you there will be three intervals), two arithmetic means will be

  • 13+25=38;
  • 38+25=63.

The only correct sequence is 13, 38, 63, 88.
