Nuetrik [128]

Answer:

p=0.8765

Step-by-step explanation:

Let the following variables be represented as below:

Total Set,t=17

Def,d=3

Not Def,n=14

Purchases,p=8

The number of ways the hotel can receive at least one defective set in a purchase of 8 sets is calculated using the combination:-

$p(\geq 1)=1-\frac{(_dC_0)(_nC_p)}{(_tC_p)}\\p=1-\frac{(_3C_0)(_14C_8)}{(_1_7C_8)}\\p=1-0.1235\\p=0.8764$

So the proability of getting at least one defective unit is 0.8765

Murrr4er [49]

Answer: $\left \{ {{l=3t+6} \atop {l+t=110}} \right.$

Step-by-step explanation:

Let be "l" the number of CDs Ms.Kitts sold last week, and "t" the number of CDs she sold this week.

You need to remember that:

1. The word "times" indicates a multiplication.

2. The word "more" indicates addition.

Then, the sentence "Last week she sold 6 more than 3 times the number of CDs that she sold this week" can be represented with equation:

$l=3t+6$

According to the information given in the exercise, the sum of the number of CDs Ms. Kitts sold last week and this week is: 110 CDs.

Since a sum is the result an Addition, you can write the following equation:

$l+t=110$

Therefore, the System of equations that can be used to find the number of CDs she sold last week and the number of CDs she sold this week, is:

$\left \{ {{l=3t+6} \atop {l+t=110}} \right.$
