Hayden is a manager at a landscaping company. He has two workers to landscape an entire park, Cody and Kaitlyn. Cody can complet
andrew11 [14]

Cody ALONE = 8 hours 
Kaitlyn ALONE = 6 hours 
Let Joseph ALONE take j hours 
Cody ALONE in 1 HOUR = 1/8 of the work Kaitlyn ALONE in 1 hour = 1/6 of the work Joseph ALONE in 1 HOUR = 1/j of the work 
Since TOGETHER they take X hours, in 1 hour TOGETHER they complete 1 / X of the work 
1/8 + 1/6 + 1/j = 1/X 
1/j = 1/X - 1/8 - 1/6 = (24 - 3X - 4X ) /24X = (24 - 7X ) / 24X 
j = 24X / ( 24- 7X ) 
After completing the work value of X will be known , calculate j from the above formula ANSWER

The probability that a person is accepted for admission to a specific university is 0.6. Determine the probability that exactly
frozen [14]

Answer: the probability that exactly two of the next five people who apply to that university get accepted is 0.23

Step-by-step explanation:

We would number of people that applies for admission at the university and gets accepted. The formula is expressed as

P(x = r) = nCr × p^r × q^(n - r)

Where

x represent the number of successes.

p represents the probability of success.

q = (1 - p) represents the probability of failure.

n represents the number of trials or sample.

From the information given,

p = 0.6

q = 1 - p = 1 - 0.6

q = 0.4

n = 5

the probability that exactly two of the next five people who apply to that university get accepted is

P(x = 2) = 5C2 × 0.6^2 × 0.4^(5 - 2)

P(x = 2) = 10 × 0.36 × 0.064

P(x = 2) = 0.23
