Mathematics

ira [324]3 years ago
7 0

Answer:

Step-by-step explanation:

From the set of 100 with 10 defective microprocessors, the probability of picking a defective one is;

10/100 = 1/10

From the set of 99 remaining and 9 defective microprocessors, the probability of picking a defective one is;

9/99 = 1/11

From the set of 98 remaining and 8 defective microprocessors, the probability of picking a defective one is;

8/98 = 4/49

From the set of 97 remaining and 7 defective microprocessors, the probability of picking a defective one is;

7/97

Adding all 4 probabilities together, we get;

1/10 + 1/11 + 4/49 + 7/97 = 0.345 or 34.5%

Which property is illustrated by the statement<br> (2+3.4)+6=2+(3.4+6)
aleksandrvk [35]

Answer:

Associative property is illustrated.

Step-by-step explanation:

we have been given:

(2+3.4)+6=2+(3.4+6)

This is the associative identity which is:

a+(b+c)=(a+b)+c

Here, we have a=2, b=3.4, c=6

On comparing the values with associative property we get:

(2+3.4)+6=2+(3.4+6)

We club two numbers b and c first and then a and b in same bracket.
