First we need the area of the whole shape (A=l*w)
A:A=7*5 or 35 (7 because you add 3 and 4)
B:A=3*4 or 12
C:A=4*4 or 16
D:A=3*9 or 27 (9 because you add 5 and 4)

So the whole area is 35+12+16+27 = 90

Then we do the part divided by the whole to find probability
=27/90 which can be simplified to 3/10

Hope this helps

The probability the point will be in the region labeled D is 3/10.

What is the probability?

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty.

The area of the whole region is;

[tex]\rm= (5+4)(3+4+3)\\\\=9 \times 10\\\\=90[/tex]

The area of the region D is;

[tex]=3(5+4)\\\\=3\times 9\\\\=27[/tex]

The probability the point will be in the region labeled D is;

[tex]\rm Probability =\dfrac{Region \ D}{Whole \ region }\\\\Probability =\dfrac{27}{90}\\\\Probability =\dfrac{3}{10}[/tex]

Hence, the probability the point will be in the region labeled D is 3/10.
