There are 9 counters. 4 red. 2 blue. 3 yellow. 2 counters are picked at random. what is the probability that at least 1 yellow counter is picked?

won't that be plagrisim thought?

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
