Abag contains 30 lottery balls numbered 1-30 a ball is selected replaced then another is drawn find each probability p ( and even,then odd ) p ( 7, then a number greater than 16)p ( a multiple of 5, then a prime number ) p ( two even number )

Given : A bag contains 30 lottery balls numbered 1-30 a ball is selected replaced then another is drawn.

To find : Each probability  

1) p ( and even,then odd )  

2) p ( 7, then a number greater than 16)

3) p ( a multiple of 5, then a prime number )  

4) p ( two even number )

Solution :

1) There are 15 even numbers and 15 odd numbers.

Probability of getting even first then odd is

2) Number greater than 16 out of 30 are 14.

Probability of getting 7 first then a number greater than 16 is

3) Multiple of 5 - 5,10,15,20,25,30=6

Prime numbers - 2,3,7,9,11,13,17,19,23,29=10

Probability of getting a multiple of 5, then a prime number  is

4) There are 15 even numbers.

Probability of getting  two even number is

#1) 5/20
#2) 7/300
#3) 3/50
#4) 5/20

Explanation
For #1:
There are 15 even numbers out of 30.  Since it is replaced before drawing the second ball, there will be 15 odd numbers out of 30.  This gives us
15/30(15/30) = 225/900 = 5/20.

For #2:
There is 1 7 out of 30; then there are 14 numbers greater than 16 out of 30:
1/30(14/30) = 14/900 = 7/300

For #3:
There are 6 multiples of 5 out of 30; then there are 9 prime numbers out of 30:
6/30(9/30) = 54/900 = 3/50

For #4:
There are 15 even numbers out of 30; then there are still 15 even numbers out of 30:
15/30(15/30) = 225/900 = 5/20

answer are given below.

Explanation:

a) One nineteenth-century ideology that likely influenced the various forms of political activism is the financial condition of middle class women that drive the wave of political movements in the females in order to fight for their rights.
