Question

A bag contain some red and green beads . Total no of beads is 20. The probability of getting a red from the bag is 3/5. a) What is the probability of getting a green bead from the bag? b)How many green beads are there?​

Answer 1

Probability of picking a red bead is 2/3

Total number of beads = 18

So

2/3*6/6=12/18

So there are 12 red beads out of 18

That means there are 18-12= 6 green beads

a) Probability of picking green beads = 6/18= 1/3

b) As we have already proved that there are 12 red beads.

c) 18-12= 6 green beads
