. he has a total of 800 cards in his collection.
how many cards in robs collection feature outfielders?
rob has cards that feature outfielders.

Explanation:

Step1: Calculate the percentage of out - fielders' cards

The sum of the percentages of pitchers' and infielders' cards is $30\%+42\% = 72\%$. The percentage of out - fielders' cards is $100\% - 72\%=28\%$.

Step2: Calculate the number of out - fielders' cards

We know the total number of cards is 800. The number of out - fielders' cards is $800\times28\%=800\times0.28 = 224$.

Answer:

224
