Answer:
Step-by-step explanation:
Given
17 % of the drivers stopped have invalid licenses
n=24 drivers are stopped
using Binomial distribution

here p=0.17
q=1-0.17=0.83
(a)none will have valid license i.e. r=0

(b)Exactly one have invalid license i.e. r=1


(c)At least 2 will have invalid license i.e. 



It’s actually 50% because you have to make a proportion 1/2=x/100 multiply the numerator 1 by the denominator 100 and you got 100 then divide it by the other denominator which is 2 so 100 divided by 2 is 50 fill 50 in for x which is 50/100 which means 50%
Is that just the question? I can help you out but it doesn’t make any sense.
This is an obtuse triangle because one angle of it is greater than 90 degrees :)
(_/18+2_/3)^(2
=(3_/2^(2 + (2)(2_/3)(3_/2) + 2_/3^(2)
=18+ 12_/6 +12
=30+12_/6
hope this helps
