Answer:

0.4

Explanation:

The number of ways to select 3 points out of 5 points:

N1 = 5C3 = (5 x 4 x 3)/(1 x 2 x3) = 10

The number of ways to select 3 points out of 4 points that are already collinear:

N2 = 4C3 = (4 x 3 x 2)/(1 x 2 x 3) = 4

=> The probability of selecting 3 points that are collinear:

P = N2/N1 = 4/10 = 0.4

Good day, Harry!
