These were the choices I found on the internet:
0.1135
0.2450
0.9423
<span>0.9932
Other sources can confirm that it is not the second choice. So I'd say it's the third one. Multiply the 98% to the 25% chance of having no allergy to get 0.2450. And for the 0.26, 98% times the 2% percent of error add this to the percent of having no allergy - 0</span>.245 / 0.26 = 0.9423 or 94.23%
Working together with others instead is called teamwork
The subject is the young boy. We know this because the sentence is about what the young boy is doing.
