Answer
a) $\frac{27}{64}$
b) $\frac{37}{64}$
c) $\frac{1}{64}$
d) $\frac{63}{64}$
Work Step by Step
a) $\frac{3}{4} \times \frac{3}{4} \times \frac{3}{4} = \frac{27}{64}$
b) $1- \frac{27}{64} = \frac{37}{64}$
c) $\frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} = \frac{1}{64}$
d) $1- \frac{1}{64} = \frac{63}{64}$
