Suppose you just received a shipment of ten televisions. two of the televisions are defective. if two televisions are randomly

amid [387]

Try this solution:

1. for probability of both televisions work:

$P_{2w}=\frac{C^2_8}{C^2_{10}}=\frac{7*8}{9*10}=0.6(2)$

2. for probability of at least on is defective (it means, the sum = one is defective and two are defective):

$P_{1d}=\frac{C^1_2C^1_8}{C^2_{10}}=\frac{4*8}{9*10}=0.3(5)$ - for P(1defective);

$P_{2d}=\frac{C^2_2}{C^2_{10}}=\frac{2}{9*10}=0.0(2)$ - for P(2defective);

totaly for at least one is defective:

$P_{at \ least \ 1 \ d}=P_{1d}+P_{2d}=\frac{16}{45} +\frac{1}{45} =0.3(7)$

4 2/3 divide by 1 2/3

sladkih [1.3K]

Answer:

14/5

Step-by-step explanation:

I'd suggest rewriting both mixed numbers as improper fractions. Then we'd have:

14/3 and 5/3

Dividing 14/3 by 5/3 is equivalent to dividing 14 by 5, since the denominators are the same (3).

Quotient is 14/5.
