Suppose you have a bag containing 15 red beads, 12 white beads and 8 black beads. You are going to draw one bead out of the bag.

iren [92.7K]

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 ) = $\frac{n(E_{1} )}{n(S)}$

$P(E_{1}) = \frac{8}{35}$

Probability of draw a white bead P( E2 ) = $\frac{n(E_{2} )}{n(S)}$

$P(E_{2}) = \frac{12}{35}$

probability that you draw a black bead or a white bead that is P(E1 U E2)

and E1 n E2 = ∅ (disjoint events)

Axiom of union

$P(E_{1}UE_{2} ) = P(E_{1})+P(E_{2}) - P(E_{1}nE_{2})\\$

E1 n E2 = ∅ ⇒ P(E1 n E2) = p(∅) = 0

$P(E_{1}UE_{2} ) = P(E_{1})+P(E_{2}) - 0$

$P(E_{1}UE_{2} ) = \frac{8}{35} +\frac{12}{35}$

$P(E_{1}UE_{2} ) = \frac{20}{35}$

$P(E_{1}UE_{2} ) = 0.571$

Solve the following equation 4 x + 10 = 66

Orlov [11]

-> 4x= 66-10

-> 4x= 56

-> x= 56/4

-> x= 14

What is the lateral area and surface area? If you amswer correctly i will mark it as brainliest

mariarad [96]

Answer:

Lateral area:

L = πdh = 3.14*12*10 = 376.8 in²

Total surface area:

S = L + 2*πd²/4
S = 376.8 + 3.14*12²/2 = 602.9 in² (rounded)

How many nanometers are in 1.7 meters and 1.52 meters

Doss [256]

It's quite easy to calculate - one meter is billion nanometers (1 000 000 000), so:

- 1.7 meters = 1 700 000 000 nanometers
- 1.52 meters = 1 520 000 000 nanometers
