Container 1 has 8 items, 3 of which are defective. Container 2 has 5 items, 2 of which are defective. If one item is drawn from
e-lub [12.9K]

Answer:

The required probability is \frac{19}{40}

Step-by-step explanation:

The probability of obtaining a defective item from container 1 is P(E_1)=\frac{3}{8}

The probability of obtaining a good item from container 1 is P(E_1)=\frac{5}{8}

The probability of obtaining a defective item from container 2 is P(E_1)=\frac{2}{5}

The probability of obtaining a good item from container 2 is P(E_1)=\frac{3}{5}

The cases of the event are

1)Defective item is drawn from container 1 and good item is drawn from container 2

2)Defective item is drawn from container 2 and good item is drawn from container 1

Thus the required probability is the sum of above 2 cases

P(Event)=\frac{3}{8}\times \frac{3}{5}+\frac{5}{8}\times \frac{2}{5}=\frac{19}{40}

What is the value of x...<br><br> 5(x-5)=3(x-7)
timurjin [86]

Answer:

x=2

Step-by-step explanation:

5(x-5)=3(x-7)

Distribute

5x-25 = 3x-21

subtract 3x from each side

5x-25-3x = 3x-21-3x

2x-25 = -21

Add 25 to each side

2x-25+25 = -21 +25

2x=4

Divide by 2

2x/2 =4/2

x=2
