The area of the square is d^2. The area of the circle sandbox is πr^2=πd^2/4. So the area of play area only is equal to square area minus circle area which is d^2-πd^2/4.

PilotLPTM [1.2K]
18 choose 7 
=C(18,7)

OR
18 choices for first passenger,
17 choices for second passenger,
....
12 choices for 7th passenger,
so total = 18*17*16...12
but there are 7! ways to order the 7 passengers, so
number of groups
=18*17*16...12/7!
=31824   as well

0.3% = 0.003..." of " means multiply
0.003(200) = 0.6 <==

0.85% = 0.0085
0.0085(600) = 5.1 <==

what u can do to turn the percents to decimals is divide by 100.
0.3 / 100 = 0.003 and 0.85 / 100 = 0.0085
or u can move the decimal two spaces to the left
