The probability that at least one child among the 3 will get influenza is 0.07.
<h3>Define probability.</h3>
The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.
Given,
3 children in a village ages 3, 5, and 7 are vaccinated with the qiv vaccine
Probability that at least one child among the 3 will get influenza
P(at least one child among the 3 will get influenza)
= 1 - P(no one have influenza)
= 1 - (1- 0.0.378)(1-0.017)²
= 1 - 0.93
= 0.07
The probability that at least one child among the 3 will get influenza is 0.07.

Answer:
50.4 km (Answer B)
Step-by-step explanation:
From this information, we are able to create a proportion, 2cm/21km= 4.8cm/x km (x representing the actual distance). After cross-multiplying and simplifying, you get an answer of 50.4km. Hope this helps!
Answer:
A) 1/6
Step-by-step explanation:
Common Ration means you need to divide second term/first term, third term/2nd term
12/72 = 1/6
2/6 = 1/6
Therefore the common ratio is 1/6

6*x=6x or x
Person 1 takes 3 hour 10 minutes to complete 9 procedures
<em><u>Solution:</u></em>
From given question,
Person 2 takes 30 minutes per procedure
Person 1 writes internal operating procedures 3 times faster than Person 2
So we get, Person 1 takes 3 times faster than Person 2
Person 1 takes 10 minutes per procedure
But two of the procedures for Person 1 took an hour each
So person 1 takes 60 minutes each for two of procedures ( since 1 hour = 60 minutes )
<em><u>Calculate how long it took Person 1 to complete 9 procedures:</u></em>
So for first 7 procedures person 1 would take 10 minutes per procedure and for last two procedures person 1 would take 60 minutes per procedure
We know that,
1 hour = 60 minutes
Therefore,
190 minutes = 60 minutes + 60 minutes + 60 minutes + 10 minutes
190 minutes = 1 hour + 1 hour + 1 hour + 10 minutes = 3 hour 10 minutes
Therefore Person 1 takes 3 hour 10 minutes to complete 9 procedures
