There are 12 beads in a bag. 7 of the beads are red. 3 of the beads are green. 2 of the beads are yellow. Lucy takes at random a bead from the bag and keeps it. Then Julian takes at random a bead from the bag. Work out the probability that the beads they take are not the same colour.

Answer 1

Answer:

• probability of getting red beards is
• $12 \div 7$
• probability of getting red is
• $12 \div 3 = 4$
• probability of getting yellow ball is
• $12 \div 2 = 6$
• probability of getting random ball is
• $6 + 7 + 4 = 17$
• 12÷x
