24 + 4pi

This is because each side is 8 and the arc (using the perimeter of a circle formula) is 4pi.

Edited for perimter:
 3 sides at 8 yards each = 8*3 = 24 yards


 circumference of circle:  diameter x PI
   8 x 3.14 = 25.12

25.12 / 2 = 12.56

total perimeter = 24 + 12.56 = 36.56 yards  ( round answer as needed)

A fair coin is tossed 20 times. The probability of getting the three or more heads in a row is 0.7870 and the probability of get
adelina 88 [10]

Answer:

The  value is  P( H \  n \  T ) =  0.6049

Step-by-step explanation:

From the question we are told that

   The  number of times  is  n  =  20  

   The probability of getting three or more heads in a row is  P(H) =  0.7870

   The probability of getting three or more heads in a row or three or more tails in a row is    P(H \ u \   T )  =  0.9791

Generally given that it is a fair coin , then   P(H) = P(T) =  0.7870

Here  P(T) is  probability of getting three or more tails  in a row

Generally  the probability of getting three or more heads in a row and three or more tails in a row is mathematically represented as

        P( H \  n \  T ) =  P(H) + P(T) -  P( H \  u \  T )

=>   P( H \  n \  T ) =  0.7870  + 0.7870 -  0.9791

=>   P( H \  n \  T ) =  0.6049
