 Probability  What is the probability that a dart tossed at random will land in the yellow area of the figure above.
 Step 1:  Find the area of the large rectangle. Step 2. Find the Area of The yellow rectangle. A(1) = lw   A(1) = 10(5) A (1)= 50  square units A (2)= lw   A (2)= 4(7) A(2) = 28 square units Step 3: Divide the part by the whole 28/50 14/25 probability of landing in the yellow area.  Step 1:  Find the area of the large circle. The large circle's radius is 7 Step 2. Find the Area of the blue area. Subtract the area of the white circle from the area of the large circle.  The radius of the white circle is 1 2 A = pr                   2 A = p7 A = 49p 2       A = 49p - pr A = 49p- 1p A = 48p Step 3: Divide the part by the whole 48p/49p 48/49 probability of landing in the blue area.   The square is divided by the diagonal.  The diagonal divides the square into two equal parts.  Therefore, the probability of a dart landing in the green area is 1/2. The circle is divided into four equal parts.  The red section is 1/4 of the circle. Therefore, the probability that a dart will land in the red area is 1/4. The circle above is divided into six equal parts; two of the part are red.  The probability that a dart will land in a red area is 2/6 or 1/3. The circle above is divided into three equal parts; two of the parts are red.  The probability that a dart will land in the red area is 2/3. The circle above is divided into six equal parts.  Three of the parts are red.  The probability that a dart will land in the red area is 3/6 or 1/2. The probability that a dart will land in the red area is 1/3.  The probability that a dart will land in the white area is 2/3.
