Data
• 54% prefer candidate A
,
• Poll of 11 voters
,
• Probability that 10 of 11 prefer candidate A.
Procedure
We have to use combination to solve this exercise:
[tex]11C10\times0.54^{10}\times(1-0.54)^{11-10}[/tex]
Simplifying and solving:
[tex]=11\times0.54^{10}\times(0.46)^1[/tex][tex]=11\times0.54^{10}\times0.46[/tex][tex]\approx0.0107[/tex]
Answer: 0.0107
