A composite number is a positive integer. which is not prime (i.e., which has factors other than 1 and itself). The first few composite numbers (sometimes called "composites" for short) are 4, 6, 8, 9, 10, 12, 14, 15, 16, ... (OEIS A002808), whose prime decompositions are summarized in the following table.
Answer:
Answer = 126 square inches
Step-by-step explanation:
Square area formula is Area = s^2 (replace the s with the side length)
Square area --> Area = 4^2 Area = 16in
Parallelogram area formula is Area = h * b (replace h with height length and replace b with base length)
Parallelogram area --> Area = 3.5 * 10 Area = 35
Rectangle area formula is Area = w * h (replace width and height)
Rectangle area --> Area = 12.5 * 6 Area = 75
Then add them all up 75 + 35 + 16 = 126 square inches
Since 5 winning numbers are draw and there are exactly 2 winning numbers, the other 3 numbers chosen have to be incorrect.
The 2 numbers picked right, there are 5C2=10 different possibilities.
The other 3 numbers are just picked from the rest of the 32 numbers. Getting there are 32C3=4960 different possibilities.
For each set of 2 correct winning numbers, you could have the 4960 different losing numbers to match up to make a unique set. This meant that there are 4690*10=46900 different total possibilities.
Now the total different outcomes of how you can choose the numbers are 37C5=435897 outcomes.
Now the way to find probabilities is want/total
The want is 46900 and the total is 435897
Doing the division you get the number rounded to the nearest thousandths as 0.107 or in percent form as
10.759% chance of picking exactly 2 winning numbers.
This seems like a competition problem of some sort therefore I assume that you already know what combinations in form nCk and permutation in form nPk means.
