A bag contains 8 red, 4 blue, and 4 yellow marbles.
What is the probability of randomly choosing 2 blue marbles without replacement?
Write your answer as a decimal. Round to the nearest hundredth if needed.

Respuesta :

bags = 8+4+4=16
firs step
p1=4/16
second step
p2=3/15
P=4/16*3/15=1/4*1/5=1/20=0,05 - correct answer

total probability at first event: 16

P(R) = 8/16

P(B) = 4/16

P(Y) = 4/16

the second event

P(B)  = 3/15

P( B in B) = P(B)1 * P(B)2 = 3/15 * 4/16 = 1/20
