Answer:3/20
Step-by-step explanation:
Heads=Boy
Tails=Girl
If the first 3 students are boys, all 3 coins must be heads.
Because in 3 of these experiments, the coins all land on heads, and there are 20 experiments completed, 3 out of the 20 experiments are 3 boys; 3/20.
The answer is x = (C-By)/A
Part/whole = percent/100
REMEBER THIS: 100 WILL ALWAYS BE THE TOTAL OF THE PERCENT!!!!!!!
So you multiply 24 ˣ 100 =2400/75 = 32
Area of sq.=1x1=1
Area of 4triangle=4(0.5x1x1)=2
Area of pyramid =1+2=3
