Question

The staff at a company includes: 1 manager, 2 shift supervisors, 2 engineers, 10 technicians, and 25 production operators. If a person is selected at random, what is the probability that he/she is a technician or production operator?

Answer 1

The probability of he/she is a technician or production operator will be 7/8.

What is probability?

The probability of an event occurring is defined by probability.

If you flip a coin, the likelihood that it will land on its head or tail is nothing more than the chance that either the head or the tail will occur.

Given,

Event 1 = selection of technician

Event 2 = selection of production operator

Since both events are independent and nothing has common in between

So,

P(1 or 2 ) = p(1) × p(2)

So,

probability (technician or production operator) = probability of technician × probability of production operator.

Probability (technician or production operator) = 10/40 + 25/40 = 7/8

Hence the probability of he/she is a technician or production operator will be 7/8.
