Question

Suppose six coins are flipped. Then the probability of getting at least one tail is

• A. $(\frac{71}{72})$
• B. $(\frac{53}{54})$
• C. $(\frac{63}{44})$
• D. $(\frac{1}{12})$

Answer 1

Answer: (C)

$(\frac{63}{44})$

Answer 2

The total number of possible outcomes when flipping six coins=$2^6=64$
Probability that no tail occurs=$\frac{1}{64}$
So, Probability of occurring at least one tail=1-\frac{1}{64}$$=\frac{63}{64}
The correct option is (C): $(\frac{63}{44})$
