Neighborhood A: 30 homes and increases by 20% per year
Neighborhood B: 45 homes and increases by 3 per year.

N.A = 30 (1.20)^t
N.B = 45 + 3(t)

t = 5

N.A = 30(1.20)^5 = 30(2.48832) = 74.65 or 75
<span>N.B = 45 + 3(5) = 45 + 15 = 60</span>

Mixed in a drawer are 44 blue​ socks, 88 white​ socks, and 44 gray socks. You pull out two​ socks, one at a​ time, without looki
MrRissso [65]

Answer:

The probability of getting 2 socks of the same color is 1/3.

Step-by-step explanation:

In the drawer,

Number of blue socks = 4

Number of white socks = 8

Number of gray socks = 4

Total number of socks  = 4 + 8 + 4 = 16

Total ways to select 2 socks form 16 socks is

^{16}C_2=\dfrac{16!}{2!(16-2)!}=120

Total ways to select 2 socks of the same color is

T = Possible ways of (2 blue + 2 white +2 gray) socks

  = ^{4}C_2+^{8}C_2+^{4}C_2

  = 6+28+6

  = 40

The probability of getting 2 socks of the same color is

Probability=\dfrac{\text{Total ways to select 2 socks of the same color}}{\text{Total ways to select 2 socks form 16 socks}}

Probability=\dfrac{40}{120}

Probability=\dfrac{1}{3}

Therefore, the probability of getting 2 socks of the same color is 1/3.
