Answer: 32%

=======================================

Step-by-step explanation:

There are 10 cards total. Of which, 8 are not blue. You can think of it as "there are 2 blue, so 10-2 = 8 are not blue", or you can count out the non-blue cards. The first option is faster in my opinion.

The probability of not getting blue is 8/10 = 0.80

After picking a first card and then putting it back, we will still have 10 cards. There are 4 pink cards out of this total, so 4/10 = 0.40 is the probability of getting a pink card.

--------

Multiply the two values we found earlier

0.80 * 0.40 = 0.32 = 32/100 = 32%
