There are 5 cards with a picture of a rose and 1 card with a picture of a daisy.

olga keeps all the cards face down on the table with the picture hidden and mixes them up she turns over one card and finds the picture of a rose on it.

she removes this card from the table and turns over another card without looking.

what is the probability that the card from the table and turns over another card without looking.

what is the probability that the card that olga turns over has a rose on it?

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event a↵ect the mean and standard deviation of the wait time until success?
