The correct answer is 598
Answer:
Step-by-step explanation:
Points are collinear when they are on the same line.
The diagram has no line going through both A and T, so any choice with that pair of points must be discarded. (The two points A and T would define a line, but none of the other points named in the diagram are on it.)
The conditions are suitable to be modelled using a binomial distribution.
p=0.43
n=15
x=5
P(x=5)
=C(15,5)*0.43^5*(1-0.43)^(15-5)
=15!/(5!(15-5)!)*0.43^5*(1-0.43)^(15-5)
=3003*0.0147008*0.003620333
=0.1598
