Question

A RECENT SURVEY FOUND THAT THE AGES OF WORKERS IN FACTORY ARE DISTRJBUTED AS

AGE IN YRS 20-29,30-39.40-49,50-59,60 AND ABOVE

NO.OF WORKERS 38,27,86,46,3

IF A PERSON IS SELECTED AT RANDOM FIND THE PROBABILITY THAT THE PERSON IS

1. 40 YRS OR MORE

2.UNDER 40YRS

3.UNDER 60 BUT NOT OVER 39YRS

Answer 1

Answer:

Step-by-step explanation:

1. P( worker aged 40 or more) = 135/200 = 27/40

2. P(worker aged under 40) = 65/200 = 13/40

3. P(worker aged below 60 but not over 39) = 13/40

Hope for brainliest!!!

Answer 2

Given:

We have given

Age in years: 20-29,30-39.40-49,50-59,60 AND ABOVE

NO.OF WORKERS 38,27,86,46,3

To Find:

Probability of different possibilities?

Step-by-step explanation:

• First of all, we find the total number of workers by adding all the workers given to us which is given by

• Total no. of workers=38+27+86+46+3=200

          Now we have that a person is selected at random from given workers

• 1) Find the probability the person is 40 years or more in age?

       Total number of worker=200

       Number of people more then age 40 =86+46+3=135

• Hence probability is given by the formula

         $P(E)=\frac{\textrm{no. of favorable outcome}}{\textrm{total no. of outcome}} \\\\P(40 years, or more)=\frac{135}{200} =\frac{27}{40}$

• 2) Find the probability the person is under 40?

       Total number of worker=200

       Number of person under age 40 =38+27=65

• Hence probability is given by the formula

         $P(E)=\frac{\textrm{no. of favorable outcome}}{\textrm{total no. of outcome}} \\\\P( less,40 years)=\frac{65}{200} =\frac{13}{40}$

• 3) Find the probability the person is under 60 but not over 39 years?

      Total number of worker=200

      Number of a person under age 40 over 39 years =86+46=132

• Hence probability is given by the formula

        $P(E)=\frac{\textrm{no. of favorable outcome}}{\textrm{total no. of outcome}} \\\\P( less,60 years)=\frac{132}{200} =\frac{66}{100}$
