Answer:
The probability is 0.05 or 5%
Step-by-step explanation:
Of 6 cars the probability of 3 being a lemon is:
[tex]frac{{3!3!}{6!}} [\tex]
Picking the first one a lemon is [tex]frac{{3}{6}} [\tex] , the second one also lemon [tex]frac{{2}{5}} [\tex] and the third one [tex]frac{{1}{4}} [\tex].
[tex]frac{{3*2*1}{6*5*4}} [\tex] can be rearanged as
[tex]frac{{3!3!}{6!}} [\tex]
7.) (36+42) x 24 / 2 = 936
8.) (11+14) x 10 / 2 = 125
9.) 16 x 9 / 2 = 72
10.) 21 x 32 / 2 = 336
