"What is the probability that the next two employees that join the office staff will take the bus"
castortr0y [4]

Answer:

The correct option is A.

Step-by-step explanation:

Consider the complete question is "The table shows the transportation method used by the employees in an office.

Transportation   Number  of employees

      Car                      18

      Bus                       6

     Walk                      6

what is the probability that the next two employees that join the office staff will take the bus? A.0.04, B.0.12, C.0.33, D.0.36.

Total number of employees = 18 + 6 + 6 = 30

The probability that the employees take the bus = \frac{6}{30}=0.2

The probability that the employees that join the office staff will take the bus is

Probability=(0.2)\times (0.2)=0.04

Therefore, the correct option is A.

The number of girl child per family was recorded for 1000 families with 3 children. The data obtained was as follows: [2] Number
ira [324]

Answer:

a.\ Probability = 0.426

b.\ Probability = 0.574

Step-by-step explanation:

Given

Total\ Families = 1000

Number of Girls :      0 ---->  1 -----> 2   ------->3

Number of Families: 112 -> 314 --> 382 ---> 192

Solving (a): At most one girl

From the table, the number of families with at most one girl is: 112 + 314

i.e.

Number of Girls :      0 ---->  1

Number of Families: 112 -> 314

So, we have:

At\ Most\ One\ Girl = 112 + 314

At\ Most\ One\ Girl = 426

The probability is then calculated as:

Probability = \frac{At\ Most\ One\ Girl}{Total}

Probability = \frac{426}{1000}

Probability = 0.426

Solving (b): More girls

From the table, the number of families with more girl is: 382 + 192

i.e.

Number of Girls :      -----> 2   ------->3

Number of Families: --> 382 ---> 192

So, we have:

More\ Girls = 382 + 192

More\ Girls = 574

The probability is then calculated as:

Probability = \frac{More\ Girls}{Total}

Probability = \frac{574}{1000}

Probability = 0.574
