Answer:

C. 1023/1024

Read Explanation:

ഒരു fair coin 10 പ്രാവശ്യം toss ചെയ്യുമ്പോൾ,

“at least one head” എന്നത് എളുപ്പത്തിൽ കണ്ടുപിടിക്കാൻ complement ഉപയോഗിക്കാം.

Step:

P(at least one head)=1P(no heads)P(\text{at least one head}) = 1 - P(\text{no heads})
“No heads” എന്നത് → എല്ലാം tails

P(all tails)=(12)10=11024P(\text{all tails}) = \left(\frac{1}{2}\right)^{10} = \frac{1}{1024}

Final:

P(at least one head)=111024=10231024P(\text{at least one head}) = 1 - \frac{1}{1024} = \frac{1023}{1024}

Answer:

10231024\boxed{\frac{1023}{1024}}
