The probability that at least 11 of them graduated is 0.7739 if graduation rate is 92.5%.
Given that graduation rate is 95.2%.
We are required to find the probability that out of 12 selected candidates atleast 11 should be graduated.
Probability is basically the chance of happening an event among all the events possible. It cannot be negative. It lies between 0 and 1.
Probability=Number of items/ Total items.
Probability that atleast 11 will be graduated out of 12 selected candidates is as under:
It will be a binomial distribution.
So,
P(X>=11)=
=12*0.4241*0.075+1*0.3923
=0.3816+0.3923
=0.7739
Hence the probability that at least 11 of them graduated is 0.7739 if graduation rate is 92.5%.

The area of the given shape is 220.24 square units.
Step-by-step explanation:
Step 1;
Area of given shape = Area of the entire rectangle - Area of the rectangle - Area of the triangle.
The entire rectangle measures a length of 12 feet and a width of 5 feet. The area of any given rectangle is the multiplication of its length and width.
The area of the entire rectangle square feet.
Step 2:
A rectangle with length 2 feet and a width of 3 feet is cut out from the entire rectangle so it is subtracted from the entire rectangle's area.
The area of the small rectangle square feet.
Step 3:
The area of a triangle =
The base length of the triangle feet and the height of the triangle is 3 feet.
The triangle's area = square feet.
Step 4:
Area of the given shape = square feet.
So 48 square feet of outdoor carpet will be needed.
