we needed to eliminate w, do so by diving both sides by w and obtain the above result :)
Hope this helps.
Answer:
2 students out of 20 have blonde hair.
Step-by-step explanation:
20 was the total number if u divide 20 ÷ by 10 = 2
so 2 is 1/10
because is only 1 out of 10
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.
