*13. Baking Afterrollingthedoughintoa9-inchby12-inchrectangle,aboycutsas (120) many biscuits with a 3-inch diameter as possible. His little sister comes and touches
the dough. What is the probability that she did not touch a biscuit?
*14. Error Analysis Two students find the probability of landing in the shaded region. (120) Which student is correct? Explain the error.
13 in.
Student A
A = _1 (10)(7) = 35 2
A = 132 = 16_9
P(shaded)= 35 169
Student B
A = _1 (10)(7) = 35 2
__ P(shaded)=1- 35 =134
A=132 =169

*18. Multi-Step A game uses a large square game board that is divided into congruent (120) smaller squares. The probability of landing on one of those smaller squares is _1 .
Each of the smaller squares has area 49 square millimeters.
a. What is the probability of not landing on that square the next time?
4
b. What is the area of the larger square?
