Question

A box contains 8 black beads and 12 white beads. Another box contains 9 black beads and 6 white beads. One bead from
each box is taken
(a) What is the probability that both beads are black
(b) What is the probability of getting one black bead and one white bead
12]​

Answer 1

Answer:

17/35 is the probability that both beads are black.

Answer 2

Answer:

(a) 17/35

(b)2/35

Step-by-step explanation:

Total Outcome in the First Box= 8 black beads+ 12 white beads= 20 beads

Total Outcome in the Second Box= 9 black beads+ 6 white beads= 15 beads

Outcome of both boxes= 20+15= 35 beads

(a)Both the beads are black= 8+9= 17 black beads

                                       P(E)= 17/35

(b)One black bead and one white bead= 1+1

                                                           P(E)= 2/35
