What is the probability of drawing an even numbered card, keeping it, and then drawing another even numbered card from a stack of 24 cards numbered 1 to 24?

Rockwell hardness of pins of a certain type is known to have a mean value of 50 and a standard deviation of 1.1. (round your answers to four decimal places.) (a) if the distribution is normal, what is the probability that the sample mean hardness for a random sample of 8 pins is at least 51?
