Step-by-step explanation:

Serial numbers for a product are to be made using 2 letters followed by 4 numbers. If the letters are to be taken from the first 6 letters of the alphabet with no repeats and the numbers are taken from the digits 0 through 9 with no repeats, how many serial numbers can be generated?

2 letters of 6 AND 4 numbers of 10

As it is ordered, it's a permutation, so:

₆P₂ AND ₁₀P₄ = ₆P₂*₁₀P₄ = 6.5.10.9.8.7 = 151200
