From a bag with 5 blue and 3 white balls, in how many ways can you pick 2 blue balls and 1 white ball at once?

60ways

Step-by-step explanation:

This has to do with selecting whereas combination deals with selection. If we are selecting r objects from the total number of n objects, we will have nCr = n!/(n-r)!r!

If we are picking 2 blue balls from 5red balls, we have 5C2 = 5!/3!2!

5C2 = 5×4×3!/3!2!

5C2 = 10ways

Similarly, picking 1 white ball from a total of 3balls, we have 3C1

3C1 = 3×2×1

3C1 = 6ways

Picking 2 blue balls and 1 white ball at once results in 5C2 × 3C1 = 10×6 = 60ways
