Hello friend that would be the last option (3, 2)
it would be great if you gave me brainlest
Answer:
The reuired probability is 0.756
Step-by-step explanation:
Let the number of trucks be 'N'
1) Trucks on interstate highway N'= 76% of N =0.76N
2) Truck on intra-state highway N''= 24% of N = 0.24N
i) Number of trucks flagged on intrastate highway = 3.4% of N'' = 
ii) Number of trucks flagged on interstate highway = 0.7% of N' = 
Part a)
The probability that the truck is an interstate truck and is not flagged for safety is 
where
is the probability that the truck chosen is on interstate
is the probability that the truck chosen on interstate is flagged

Part 1:
Given that x represents the <span>number of apple pies that can be made and y represents the number of apple cobblers that can be made.
Given that a</span><span>n
apple pie uses 4 cups of apples and an apple cobbler
uses 2 cups of apples and there are 16 cups of apples available.
</span>A<span>n inequality to show the constraint on the amount of apples available is given by:
4x + 2y ≤ 16
</span>
Part 2:
<span>Given that an
apple pie uses 3 cups of flour and an apple cobbler
uses 3 cups of flour and there are 15 cups of flour available.
</span>A<span>n inequality to show the constraint on the amount of flour available is given by:
3x + 3y ≤ 15
Part C:
The </span><span>non negativity contraints on x and y are:
x ≥ 0 and y ≥ 0
