Answer:
Step-by-step explanation:
P(a or b) = P(a) + P(b) - P(a and b)
0.88 = 0.70 + 0.60 - P(a and b)
P(a and b) = 1.30 - 0.88 = 0.42.
So the events a and b are not mutually exclusive.
Correct option is C. He has 225 acres of land .
Let the Number of acres of land Roy have = x
As he planted corn on 1/5 of his land,
Number of acres of his land planted with corn = 1/5 × Number of acres of land Roy have
= x/5
As he planted 45 acres of his land with corn,
⇒ x/5
= 45
⇒x = 45 × 5
⇒x = 225
Therefore, number of acres of land Roy have is 225 .
