The number of passengers who choose to check luggage on a flight from Los Angeles to San Francisco is a binomial random variable with n = number of passengers on the flight. If the probability that any individual passenger checks luggage is .3, what is the probability that exactly 40 of the 100 passengers on this flight on a particular day check luggage? Round your answer to the nearest hundredth.

Which mathematical statements are true? 1) if 3 is an odd number, then 3 times 3 is an even number. 2) if 6 is less than 7, then 4 is greater than 7. 3) six is divisible by 3, and 10 is a multiple of 2. 4) the average of the data is greater than the largest value in the data, or it’s less than the largest value in the data. 5) the slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value. 6) if an equilateral triangle has equal angles, then all its angles will measure 45°.
