A coin, having probability p of landing heads, is continually flipped until at least one head and one tail have been flipped. (a) What is the probability that stop at the fifth flip? (b)Find the expected number of flips needed.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

perimeter of the base times height

step-by-step explanation:

the angles measure to 70 degrees, 70 degrees, 20 degrees, and 20 degrees
