Answer:
<em>The probability of obtaining the letter p twice is 1/121</em>
Step-by-step explanation:
<u>Probability of Recurring Events</u>
There are 11 letters in the word 'independent', one of which is the letter 'p'.
When those letters are written on individual cards and they are put into a box, there are 11 different choices to pick at random.
This means the individual probability of getting a 'p' is:
The card is reinserted into the box, leaving the sample space unaltered, thus the second card has the same probability:
We'll use the multiplication rule. Just multiply the probability of the first event by the second.
The probability of obtaining the letter p twice is 1/121
