Answer:
31.8%
Step-by-step explanation:There are 7 months that have 31 days so,
The odds the first selected month has 31 days is 7/12
The next month there are only 6 months left with 31 days of only 11 months to choose from
so the odds for the second are 6/11
To calculate the odds they BOTH have 31 months you multiply the two odds:
(7/12) x (6/11) = 42/132 = .318 so 31.8%
To find the mean you add all the numbers then divide by how many numbers there are :
8+16+12+11+8=55
in the equation there are 5 numbers, so you divide 55 by 5 :
55÷5=11
the mean is 11
