Mathematics for IGCSE & O level - Probability (Section 3 - No. 4)
In a bag, there are 5 green balls, 3 red balls, and 2 yellow balls. If Jai chooses a ball at random, replaces it, and then chooses again, what is the probability that Jai's choices are red and yellow in any order?
3/25
3/50
1/25
2/25
Forklaring
P(red then yellow) + P(yellow then red) = (3/10 * 2/10) + (2/10 * 3/10) = 6/100 + 6/100 = 12/100 = 3/25
