Q5 of 18 Page 69

A bag contains 3 red beads and 7 green beads. Another contains one red and one green more. The probability of getting a red from which bag is more?

Number of red beads in bag 1 = 3


Number of green beads in bag 1 = 7


Number of red beads in bag 2 = 4


Number of green beads in bag 2 = 8


Total number of beads in bag 1 = 10


Total number of beads in bag 2 = 12


Probability of getting a red bead from bag 1



⇒


Probability of getting a red bead from bag 2



⇒


∴ Probability of getting a red bead from bag 2 is higher.
