Printed circuit cards are placed in a functional test after being populated with semiconductor chips. A lot contains 110 cards,
Yakvenalex [24]

Answer:

The answers to the questions are;

(a) P(At least 1 defective)

= 0.9883.

(b) P(At least 1 defective)

= 0.6409.

Step-by-step explanation:

There are 110 cards and 20 defectives.

a) The probability of at least one defective is given by

P(At least 1 defective) = 1 - P(0 defective)

P(0 defective) = 20C0 × (90C0)/(110C20) = 0.0116

1 - 0.0116 = 0.9883

b) For a set of 110 boards that has 5 defective and 105 non-defective

P(At least 1 defective) = 1 - P(0 defective)

P(0 defective) = (20C0)(90C5)/(110C5) = 0.35909

1-0.35909

= 0.6409

100 POINTS!!! Which statement about rational numbers is correct?
Natasha_Volkova [10]

Answer: Rational numbers have decimal expansions that repeat or terminate.

Step-by-step explanation:

The explanation of this is the non-terminating but repeating decimal expansion means that although the decimal representation has an infinite number of digits, there is a repetitive pattern to it. The rational number whose denominator is having a factor other than 2 or 5, will not have a terminating decimal number as the result.
