According to Trains, Trains Trains, trains in Jacksonville had an on-time percentage of 79.0% in 2019. Suppose that 4 trains are randomly selected from 2019 and the number of on-time trains X is recorded. What is the probability that 3 trains are on time? Write it as 0.5^2 (even if the exponent is 1 or 0 to show the pattern 0.79^30.21^14What is the probability the other 1 trains are NOT on time? Write it as 0.5^2 (even if the exponent is 1 or 0 to show the pattern 0.21^140.79^3How many possible options are there that 3 trains are on time? i.e. think about 1st flight on time, or the second, or the third, etc. Use picture above! 40.79^30.21^1You would then multiply all answers together to find the probability.
