Afast-food restaurant runs a promotion in which certain food items come with game pieces. according to the restaurant, 1 in 4 game pieces is a winner. if jeff gets 4 game pieces, what is the probability that he wins exactly 1 prize?
(a) 0.25
(b) 1.00
(c) (41)(0.25)1(0.75)3
(d) (41)(0.25)3(0.75)1
(e) (0.75)3(0.25)1

(c)

Step-by-step explanation:

As given in the statement, we have:

Out of 4 games pieces, 1 is winner.

Probability to win =p=

Jeff has game pieces = n = sample size = 4

As we need to find the probability that he wins exactly 1 prize, we will use binomial probability here :

Evaluating at k=1, (k=1 as we need to find probability for exactly 1 prize won)

put n = 4, p =

P (X = 1) =

P =

Which is the probability that he wins exactly 1 prize and is option c.

step-by-step explanation:

the answer is 89 d

i took the test

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
