Production records indicate that 3.4% of the light bulbs produced in a facility are defective. a random sample of 25 light bulbs was selected. a. use the binomial distribution to determine the probability that fewer than three defective bulbs are found. b. use the poisson approximation to the binomial distribution to determine the probability that fewer than three defective bulbs are found. c. how do these two probabilities compare?

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
