A coin that comes up heads with probability p is continually
flipped until the pattern H, H, T appears. (That is, you stop flipping
when the most recent flip lands tails and the two immediately preceding it lands heads.) Let X denote the number of flips made. Find
E[X]. You may leave your answer in terms of an equation in E[X]
and p. solution: Note that this problem is a modified version of one
of your homework problems. Proceed using one-step arguments.

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true

step-by-step explanation:
