Using the probability concept, it is found that there is a
a) 0.2 = 20% probability that 3 is obtained.
b) 0.3333 = 33.33% probability that 6 is obtained.
c) 0.6667 = 66.67% probability of a number greater than 3.
d) 0.6667 = 66.67% probability of an even number.
A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
Item a:
There are 5 numbers greater than 1, one of which is 3, hence:
0.2 = 20% probability that 3 is obtained.
Item b:
There are 3 numbers greater than 3, one of which is 6, hence:
0.3333 = 33.33% probability that 6 is obtained.
Item c:
There are 3 even numbers, two of which are greater than 3, hence:
0.6667 = 66.67% probability of a number greater than 3.
Item d:
There are 3 numbers greater than 3, two of which are even, hence:
0.6667 = 66.67% probability of an even number.

Answer:
21.5%
Step-by-step explanation:
The first step is to find the area of the square, and then the area of the circles inside. The area of the square is the side length squared, or in this case 2304. Since the circles are inscribed in the square, they are touching the borders, and two of them perfectly cross to the other side. Therefore, the diameter of one of the circles is half of the side length of the square, and the radius is a quarter. Thus, the area of one of the circles is , which when multiplied by the 4 circles yields about 1809.557. Subtracting this from the total area of the square, you get 494.443, which when divided by the total area of the square gives approximately 21.5%. Hope this helps!
