Answer:
a) 419
b)34
c)81
d)52
Step-by-step explanation:
Let x represent the number of farmers who grew all three crops and y represent those who grew corn and oath.
This information is represented on a Venn Diagram as shown in the attachment (A)
Let us add all the regions in wheat and equate to 206.
We can now add all the regions in corns and equate to 178
We redraw the Venn diagram as shown in the attachment (B).
We can now answer the question using the second diagram:
Those who grew at least one of the three crops =exactly one +exactly two +exactly three
=121+111+93+24+9+19+34=419
a) Of the farmers, 419 grew at least one of the three crops.
b) Of the farmers,34 grew all three crops.
c) Of the farmers,81 did not grow any of the three crops.
Exactly two=9+19+24=52
d) Of the farmers, 52 grew exactly two of the three crops.
