Step-by-step explanation:
Given
P(A or B)= P(B)-P(A and B)
P(A)=1/3
P(A and B)=1/8
P(A or B)= 3/4
Required
Find P(B)
To find P(B), all we need to do is to substitute values of P(A or B) and P(A and B) in the given equation.
This goes thus;
P(A or B) = P(B) - P(A and B) becomes
Make P(B) the subject of formula
Take L.C.M
Add fractions
From the workings above, the value of P(B) using the given equation is
Answer: A=70 square units
Step-by-step explanation:
The area of a triangle can be found using the formula
Let 5=h and 7=b
Plug in the values and solve
However, since four of these triangles make up this rhombus, we can multiply the area of one of these triangles by four to find the area of the whole rhombus.
