1)

Number of unshaded regions = 40

Total number of shaded regions = 64

Probability of selecting a point in unshaded region

= Number of favorable outcomes / Total number of outcomes

= 40/64

= 5/8

2)

1 m = 100 cm

Divide both sides by 100

$\frac{1}{100} m = \frac{100}{100} cm\\ \\ \frac{1}{10^2} m = 1 cm\\ \\ 10^{-2} m = 1 cm$

$1cm=10^{-2}m$

Raise both sides to the power of 3

$1^3 cm^3=(10^{-2})^3 m^3\\ \\ 1cm^3=10^{-6}m^3\\$

Multiply booth sides by 500,000
