Step-by-step explanation:
all work is pictured and shown
the distance from (-2,2) to (5,-3) is 8.6,
(5,-3) to (-4,-1) is 9.2
(-4,-1) to (-2,2) is 3.6
8.6+9.2+3.6= 21.4
so the perimeter is 21.4
P(Tails) = 1/2
P(2 Tails) = P(Tails) * P(Tails)
P(2 Tails) = 1/2 * 1/2 = 1/4
The awnser is 4 1/6
i did this by multiplying 5/6 times 5
