Question

automobiles are randomly distributed with an average spacing of 1000 feet along a highway the probability that at least two cars are present in 1000 feet interval selected at random​

Answer 1

Answer:

1/500

Step-by-step explanation:

Average spacing of automobiles along a highway= 1000 feet

Average spacing of automobiles along a highway= 1000 feetFavourable number of cars present at 1000 feet interval selected at random = 2

Average spacing of automobiles along a highway= 1000 feetFavourable number of cars present at 1000 feet interval selected at random = 2Probability = Number of favourable outcomes

Average spacing of automobiles along a highway= 1000 feetFavourable number of cars present at 1000 feet interval selected at random = 2Probability = Number of favourable outcomes Total number of outcomes

Average spacing of automobiles along a highway= 1000 feetFavourable number of cars present at 1000 feet interval selected at random = 2Probability = Number of favourable outcomes Total number of outcomes = 2

Average spacing of automobiles along a highway= 1000 feetFavourable number of cars present at 1000 feet interval selected at random = 2Probability = Number of favourable outcomes Total number of outcomes = 2 1000

Average spacing of automobiles along a highway= 1000 feetFavourable number of cars present at 1000 feet interval selected at random = 2Probability = Number of favourable outcomes Total number of outcomes = 2 1000 = 1/500
