George is a big fan of music from the 1960s, and 22% of the songs on his iPod are Beatles songs. Suppose George sets his iPod to "shuffle," so that it selects songs randomly (assume the shuffle function permits repetition of songs). During a long drive, George plays 50 randomly selected songs. Calculate the probability that more than 30% of the 50 randomly selected songs are Beatles songs. Round your answer to four decimal places.
A textile manufacturing process finds that on average, three flaws occur per every 50 yards of material produced. What is the probability that exactly 2 flaws occur in a 50 yard piece of material? Round your answer to three decimal places with a zero to the left of the decimal. E.g., 12% would be 0.120, and 0.15551 would be 0.156.
The chances of a pine tree in a particular forest being effected by the pine beetle is 10 percent. If you randomly select 20 trees for testing, what is the probability that fewer than 2 will be infected by the pine beetle? Round your answer to three decimal places, e.g. 0.619.

Tire pressure monitoring systems (TPMS) warn the driver when the tire pressure of the vehicle is 27% below the target pressure. Suppose the target tire pressure of a certain car is 32 psi (pounds per square inch.) (a) At what psi will the TPMS trigger a warning for this car? (Round your answer to 2 decimal place.) When the tire pressure is (Click to select) : psi. (b) Suppose tire pressure is a normally distributed random variable with a standard deviation equal to 3 psi. If the car's average tire pressure is on target, what is the probability that the TPMS will trigger a warning? (Round your answer to 4 decimal places.) Probability (c) The manufacturer's recommended correct inflation range is 30 psi to 34 psi. Assume the tires' average psi is on target.
