List A contains the numbers [20,10,30], while list B contains the numbers [10,30,20,40,30]. We choose one number from list A randomly and one number from list B randomly. What is the chance that the number we drew from list A is larger than or equal to the number we drew from list B

Chance that the number we drew from list A is larger than or equal to the number we drew from list B is as

Number chosen is 30:

Number chosen is 10:

Number chosen is 20:

Step-by-step explanation:

We have , List A contains the numbers [20,10,30], while list B contains the numbers [10,30,20,40,30]. We choose one number from list A randomly and one number from list B randomly. Let's assume 3 cases for above problem:

Number chosen is 20:

We compare that 20 from list A is greater than or equal to 10 , 20 in list B . So probability that this number drew  from list A is larger than or equal to the number we drew from list B is .

Number chosen is 10:

We compare that 10 from list A is greater than or equal to 10 in list B . So probability that this number drew  from list A is larger than or equal to the number we drew from list B is .

Number chosen is 30:

We compare that 30 from list A is greater than or equal to 10 , 20, 30,30 in list B . So probability that this number drew  from list A is larger than or equal to the number we drew from list B is .

∴ Chance that the number we drew from list A is larger than or equal to the number we drew from list B is as

Number chosen is 30:

Number chosen is 10:

Number chosen is 20:

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
