Suppose 2% of all cell phone chips are defective. we randomly select 100 of the 50,000 cell phone chips produced in a day. what is the chance that 0 defective chips will be found?

To solve this problem, we make use of the Binomial Probability equation. The formula is:

P = [n! / r! (n – r)!] p^r * q^(n – r)

where,

n = the total number of samples tested = 100

r = the total number of defective chips = 0

p = probability of being defective = 0.02

q = probability of not being defective = 0.98

 

Hence, substituting the values:

P = [100! / 0! (100 – 0)!] 0.02^(0) * 0.98^(100)

P = [1] * 0.02^(0) * 0.98^(100)

P = 0.1326 = 13.26%

 

Therefore there is a 13.26% probability that 0 defective chips will be found.

The answer is 10 bud

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
