Hey There
According to me, 
no 1 is 
SQUARE
no. 2 is 
CONGRUENT
HOPE THIS HELPS
        
                    
             
        
        
        
Step-by-step explanation:
first, add the whole numbers
6 + 7 = 13
then the fractions 
3/8 + 5/6
we need to get common denominators 
do you know how to do that

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
