Two fair coins are tossed. What is the probability of getting at the most one head?
(a) `frac{3}{4}`
(b) `frac{1}{4}`
(c) `frac{1}{2}`
(d) `frac{3}{8}`
(a) `frac{3}{4}`
Explanation:
Outcomes with almost one head
= Outcomes with no head + Outcomes with 1 head
= TT,TH,HT
Now, Probability of getting atmost one head
= `"Number of Outcomes with atmost 1 head"/"Tital Number of Outcomes "`
= `frac{3}{4}`
