Question

there are 18 beaads in bag of colours red and green if we take a bead from the bag the probability being red is 2/3
a] how many red beads?
b] how many green beads?
c] what is the probability of being green beads?

Answer 1

Step-by-step explanation:

Let, A be the event - being red

nA = ?

nS = 18

P (A) = 2/3

But P(A) = nA / nS

= nA / 18

Therefore, nA / 18 = 2/3

nA = 2/3 × 18 = 12

There are 12 red beads

No. of green beads = Total no. of beads - No. of red beads

= 18 - 12 = 6

Probability of being red beads = 6/18 = 1/3
