A production process operates with 3% nonconforming parts. Every hour a sample of 50 parts is taken, and the number of nonconforming parts counted. If one or more nonconforming parts are found, the process is stopped and the quality control technician must search for the cause of nonconforming production. What is the probability that the process is stopped?

The required probability is 0.782.

Step-by-step explanation:

Since we have given that

Probability of non conforming parts = 3%

Number of parts is taken = 50

Probability of conforming parts = 100-3=97%

So, using Binomial distribution, we get that

Probability that the process is stopped is given by

Hence, the required probability is 0.782.

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
