What's the probability of flipping a coin twice and having it come up heads both times?
P(Comes up heads) =
P(1"' flip comes up heads AND 2nd flip comes up heads)=

Probability of head occurring on flip of coin twice =

Step-by-step explanation:

Step 1:

Given,

A coin is flipped 2 times. We need to find probability that head occurs both  times

Step 2 :

Probability that a head occurs when  a coin is flipped =

The probability that  head occurs when the coin is flipped again =

This is because the 2 events are independent i,e the result of  second event is not dependent on happening of the first event

Hence probability that head occurs on both the flip = × =

Step 3 :

Answer :

Probability of head occurring on flip of coin twice =
