If the pond were a rectangle, then:
length=15 m
width=6 m
We would have to calculate the perimeter of this rectangle.
Perimeter of a rectangle=2(length)+2(width)
Perimeter of this rectangle=2(15 m)+2(6 m)=30 m+12 m=42 m
We need 42 m and I only have 40 m, therefore, it would not be enough for fencing the pond.

Step-by-step explanation:
Sample size 52 card
Pay for J or Q
Pay for King or Ace
Pay for others
Therefore
Probability of drawing J or Q
Probability or drawing King or Ace
Probability or drawing Other cards
Therefore
Expected Gain is mathematically given as
Remember that
1m=100cm
8m=800cm
800m=80,000cm
Let the boy be B and the girl be G
there are six possible outcomes
BGG, GBB, GBG, BGB, BBB, and GGG
therefore the probability of getting one boy and two girls is
also the probability of getting 3 girls is
