Question

Susan has some beads in a bag.!!

5 of the beads are orange.!!
3 of the beads are purple.!!
The rest of the beads are pink. !Susan takes a bead from the bag at random.! The probability that she takes a pink bead is ⅗!How many pink beads are in the bag before Susan takes a bead?

Answer 1

12

Explanation:

If there are 5 orange beads, and 3 purple beads, that means there is 8 beads that aren't pink in the bag.

If the rest are pink, and it's 3/5, that means 8 is 2/5. Divide by 2, and 4 is 1/5.

We can conclude that there are 12 pink beads, which is 3/5 of the total beads, by adding 2/5 and 1/5 (8 and 4)

The remaining 2/5 are the orange and purple beads.
