<h3>What is probability?</h3>
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.

Answer:
There are 24 kilometre in 1 mile
There are 0.0416 miles in 1 kilometre
Step-by-step explanation:
Elena and her mom are driving 75 miles per hour
There are 5 miles approx in 8 kilometre
Therefore, in 75 miles, there are 15 equal 5 miles
Since 5 miles = 8 kilometre
15 equal 5 miles = 15 X 8 = 120 kilometre
In 1 mile, there are 120÷5 = 24 kilometre
In 1 kilometre, there are 5 ÷ 120 = 0.0416 miles
