Question

In an NBA (National Basketball Association) championship series, the team that wins four games out of seven is the winner. Suppose that teams A and B face each other in the championship games and that team A has probability 0.55 of winning a game over team B. What is the probability that team A will win the series in 6 games? What is the probability that team A will win the series? The number of surface flaws in plastic panels used in the interior of automobiles has a Poisson distribution with a mean of 0.1 Haws per panel. What is the expected number of panels that need to be inspected before a flaw is found? If 20 panels are inspected, what is the probability that the number of panels that have one or more flaws is less than 4? A multiple-choice quiz has 200 questions, each with 5 possible answers of which only I is correct. Estimate the probability that sheer guesswork yields from 25 to 30 correct answers for the 100 of the 200 problems about which the student has no knowledge?

Explanation / Answer

chegg's policy allow me to answer 1 question per post

I can gladly help you but you should post it in a new quesiton ( the other 2 question)

b)

i)

expected number = 0.1

ii)

P( x >=1 ) = 1-P( x < 1) = 1 - P(x=0)

P( x = 0 ) =[ e^-(0.1) * 0.1^0 ] / 0! = 0.9048

P( x >= 1 ) = 1 - 0.9048 = 0.0952
