Question

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: p = \frac{4}{5}

    Number chosen is 10: p = \frac{1}{5}

    Number chosen is 20:p = \frac{2}{5}

    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 p = \frac{2}{5}.

    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 p = \frac{1}{5}.

    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 p = \frac{4}{5}.

    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: p = \frac{4}{5}

    Number chosen is 10: p = \frac{1}{5}

    Number chosen is 20:p = \frac{2}{5}
