You flip a fair coin until you see three tails in a row. What is the average number of headsthat you’ll see until gettingTTT?

14

Step-by-step explanation:

From the given information:

suppose, Y is the number of times a coin is being flipped.

If the coin is flipped for the first time and we get H, then we have:

TTT =

Afterward, if we get H, then we waste two times plus the probability of this event .

Therefore, we have :

Afterward, if we get H, then we waste three times plus the probability of this event .

Therefore, we have :

If we got T at the third time, then;

T =

Thus, average number of headsthat you’ll see until gettingTTT can be expressed as:

= 14

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
