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

<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



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