Question

A fair coin is flipped 11 times exactly 9 are tails

Answer 1

The probability of having tails is 9/11

Data;

• 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 = $11-9 = 3$

The probability of having tails is calculated as

$p = \frac{9}{11}$

The probability of having head is calculated as

$p = \frac{3}{11}$

The probability of having tails is 9/11
