Answer:
i- umm- its, well i got two answers n this question as well, but umm, i think its
1 5/12 maybe
Step-by-step explanation:
Answer:
a)
And we can use the probability mass function and we got:
And adding we got:
b)
c)
And replacing we got:
d)
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Part a
We want this probability:
And we can use the probability mass function and we got:
And adding we got:
Part b
We want this probability:
And using the probability mass function we got:
Part c
We want this probability:
We can use the complement rule and we got:
And replacing we got:
Part d
The expected value is given by:
And replacing we got:
X= -4 for solving x and y= 0 for solving y
Raw material for 500 units per week = 500 x $10 = $5000
Cost of hiring 20 workers per week = 20 x 40 x 25 = $12000
Rental = $2250
Total = 5000 + 12000 + 2250 = $19 250
