The probability of having tails is 9/11

  • N = 11
  • tails = 9

Probability

This is the possibility of an event occurring. In a sample space of 11 coin flips, tails came up 9 times and head came up 3 times

Number of time head came up = [tex]11-9 = 3[/tex]

The probability of having tails is calculated as

[tex]p = \frac{9}{11}[/tex]

The probability of having head is calculated as

[tex]p = \frac{3}{11}[/tex]

The probability of having tails is 9/11
