Given:

Flipping a coin twice.

Required:

We need to find the likelihood of flipping heads twice in a row.

Step-by-step explanation:

The sample space = All possible outcomes.

The sample space, S= {TT,TH,HT,HH}


n(S)=4

Let A be the event of flipping heads twice..

The favorable outcomes = flipping heads twice.

The favorable outcomes ={HH}


n(A)=1

Consider the probability formula.


P(A)=(n(A))/(n(S))
P(A)=(1)/(4)
P(A)=0.25

The probability of flipping heads twice in a row is 0.25 which is a close value to the number 0.

This event happens least likely.

Final answer:

Flipping heads twice in a row is the least likely.

The probability of flipping heads twice in a row is 0.25.
