An accounting firm has recently recruited six graduates: three men and three women. Three of the graduates are to be selected at
solong [7]

Answer:

a) The probability tree is constructed below

b) the probability that at least two women will be selected is 0.500

Step-by-step explanation:

Given the data in the question;

a) The probability tree is as follows;

                                                 3 men, 3 women

                                                            ↓

           _______________________|________________________

            ↓                             ↓                                  ↓                               ↓

         3 men                    2 men                          1 man                        0 men

      0 women                1 woman                     2 woman                   3 women

b) the probability that at least two women will be selected

p( at least two women would be selected) = P( there are 2 women out of 3 ) + P( there 3 women out of 3

so

p( at least two women would be selected) = C

³C₂ × ³C₁ / ⁶C₃ + ³C₃³C₀ / ⁶C₃  

= 3!/(2!(3-2)!) × 3!/(1!(3-1)!)  / 6!/(3!(6-3)!) + 3!/(3!(3-3)!) × 3!/(0!(3-0)!) / 6!/3!(6-3)!)

= 3 × 3 / 20 + 1 ×  1 / 20

= 9/20 + 1/20

= 0.45 + 0.05

p( at least two women would be selected) = 0.500

Therefore, the probability that at least two women will be selected is 0.500

The cost of a parking permit consists of a one-time administration fee plus a monthly fee. a permit purchased for 12 months cost
julsineya [31]

let

x--------> the monthly fee

y--------> the administration fee

we know that

660=y+12x --------> equation 1

810=y+15x --------> equation 2

Multiply by -1 equation 1

-660=-y-12x ------> equation 3

Adds equation 2 and equation 3

810=y+15x\\-660=-y-12x\\---------\\   810-660=15x-12x\\ 3x=150\\ x=50\ dollars

Find the value of y

660=y+12x\\ 660=y+12*50\\ y=660-600\\ y=60\ dollars

therefore

the answer is

the administration fee is equal to 60\ dollars
