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



Raise both sides to the power of 3



Multiply booth sides by 500,000
