Tax returns filled manually have a 20% chance of containing errors while tax returns filled electronically have a .05% chance of containing the same if 2.7 million tax returns are filed each way how many more erroneous manually filed returns will there be than erroneous electronically filed returns

538,650

Step-by-step explanation:

We must first find how many errors there will be if filed manually and if filed electronically

Manually: 2,700,000*20% or 2,700,000*.2

540,000 errors

Electronically: 2,700,000*.05% or 2,700,000*.0005

1,350 errors

We must then find the difference; 540,000-1,350=538,650

538,650.

Step-by-step explanation:

Number of erroneous manual returns = 20% of 2.7 million

= 0.20 * 2,700,00 = 540,000.

Number for electronically returned =  2,700,000 * 0.0005 = 1350.

Difference = 540,00 - 1350 = 538,650.
