Answer:
probability that you draw a black bead or a white bead that is P(E1 U E2)
= 20/35 = 0.571
Step-by-step explanation:
Given a bag containing 15 red beads, 12 white beads and 8 black beads
n(S) = 15 + 12 +8 = 35
Let 'E1 be the event of selecting black beads and E2 be the event of selecting white beads
n(E1) = 8 and n(E2) = 12
Probability of draw a black bead P( E1 ) =
Probability of draw a white bead P( E2 ) =
probability that you draw a black bead or a white bead that is P(E1 U E2)
and E1 n E2 = ∅ (disjoint events)
<u>Axiom of union </u>
<u></u><u></u>
E1 n E2 = ∅ ⇒ P(E1 n E2) = p(∅) = 0
