Approximately 18% of the population of California is 70 years or older. In a random sample of 4, what is the provability for 3 o
Semmy [17]

Answer:

The correct response will be "0.01913".

Step-by-step explanation:

According to the question,

p - P(70 years or older)

= 0.18

n = 4

X = no. of individuals who are older than 70 years

Now,

∴ P(X=r)=n_C_r \ p^r(1-p)^{n-r}

∴ P(X=3)=4_C_3(0.18)^3(1-0.18)^{4-3}

                   =4\times (0.18)^3(0.82)^1

                   =0.01913

Lemon drops and jelly beans are mixed to make a 100 pound mix. if the lemon drops cost $1.90 per pound and jelly beans cost $1.2
vladimir1956 [14]

L = lemon drops

J = jelly beans

L +J = 100

L=100-J

1.90L + 1.20J=1.48*100

1.90(100-j) +1.20J =148

190-1.90J+1.20J=148

190-0.7J=148

-0.7J=-42

J = 60

L=100-60 = 40
