Three fair coins are flipped. What is the probability that at least 2 of them come up heads?
exis [7]

Answer:

<h3>The probability that atleast 2 of them come up heads is 0.5</h3><h3>∴ P(A)=0.5</h3>

Step-by-step explanation:

Given that three fair coins are flipped.

<h3>To find the probability that at least 2 of them come up heads:</h3>

Sample space for the given event is

S={\{HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}\}

<h3>∴ n(S)=8</h3>

Let A be the events of getting atleast 2 Heads and is given by

A = {HHH, HHT, HTH, THH}

<h3>∴ n(A)=4</h3>

Probability of Getting atleast 2 Heads in 3 Coin Tosses  is

P(A)=\frac{n(A)}{n(S)}

P(A)=\frac{4}{8}

=0.5

<h3>∴ P(A)=0.5</h3><h3>∴ the probability that atleast 2 of them come up heads is 0.5</h3>
