Trucks that travel on highways have to stop at various locations to be weighed and inspected for safe brakes and light systems. of these trucks, 76% are on interstate commerce while 24% are intrastate. of the intrastate trucks, 3.4% are flagged for safety defects compared to 0.7% of those that are on interstate business. complete parts a through c below. a. calculate the probability that a randomly chosen truck is an interstate truck and is not flagged for a safety violation. the probability is nothing. (round to three decimal places as needed.)

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

its what i use
