11) What are the possible combination outcomes when you toss a fair coin three times?

The correct answer is Option (d): $[HHH,TTT,HTH,THT,HHT,TTH,THH,HTT]$

There are 8 possible outcomes when we toss a fair coin three times.

12) What is the probability of you getting three heads straight for tossing a fair coin three times?

The correct answer is Option (c): $1/8$

The sample space for tossing a fair coin three times is,

$S=[HHH,TTT,HTH,THT,HHT,TTH,THH,HTT]$

Number of possible outcomes in sample space $n(S)=8$

Let A be the event of getting three heads.

$A=[HHH]$

Number of outcomes with three heads $n(A)=1$

We know that,

Probability = Number of favourable outcomes / Total number of outcomes

The probability of getting three heads straight for tossing a fair coin three times is,

$P[A]=n(A)/n(S)$

$=1/8$

13) What is the probability of you getting no heads at all for tossing a fair coin three times?

The correct answer is Option (c): $1/8$

The sample space for tossing a fair coin three times is,

$S=[HHH,TTT,HTH,THT,HHT,TTH,THH,HTT]$

Number of possible outcomes in sample space $n(S)=8$

Let B be the event of getting no heads at all.

$B=[TTT]$

Number of outcomes with no heads $n(B)=1$

We know that,

Probability = Number of favourable outcomes / Total number of outcomes

The probability of getting no heads at all for tossing a fair coin three times is,

$P[B]=n(B)/n(S)$

$=1/8$

Probability Puzzle 3: Flipping Coins If you flip a coin 3 times, the probability of getting any sequence is identical (1/8). There are 8 possible sequences: HHH, HHT, HTH, HTT, THH, THT, TTH, TTT Let's make this situation a little more interesting. Suppose two players are playing each other. Each player choses a sequence, and then they start flipping a coin until they get one of the two sequences. We have a long sequence that looks something like this: HHTTHTTHTHTTHHTHT.......
