Problema Solution
If you have two bags of balls numbered 1-5, what is the probability of drawing one ball from each bag that adds equals 9?
Answer provided by our tutors
the number of all the possible drawings is: 5*5 = 25
the number of drawings, one ball from each bag that adds equals 9 is 2: 4 and 5, 5 and 4
P(rawing one ball from each bag that adds equals 9) = 2/25 = 0.08 or 8%.
