Answer:0.0081 or 0.81%
Step-by-step explanation:
The required probability is P(3,5,0.1)= C5 3 * p^3*q^2, where
C5 3= 5!/3/2=4*5/2=10
p is the probability that one randomly selected calculator is defective= 10%=0.1
q is the probability that one randomly selected calculator is non-defective.
q=1-p=1-0.1=0.9
So P(3,5,0.1)= 10*0.1^3*0.9^2=0.01*0.81=0.0081

1 Acre = 43560 square feet
1 Ton = 2000 pounds
320 Acres = 320 * 43560 square feet = 13939200 = <span>1393.92 * 10,000
</span>1393.92 *40 pounds needed = 55756.8
55756.8 / 2000= <span>27.8784 </span>
