1/4 as a decimal is 0.25 (divide one by four). You can also multiply 1/4 by 52, but converting it into a decimal is typically easier.
"Of" typically means multiply, so multiply 52 * 0.25 to get the product 13.
For Option A., solve for 0.25 * 52, the final result should be 13.
For Option B., convert 4% into a decimal by dividing 4 over 100, you will get 0<span>.04, multiply 0.04 * 52 to get 2.08. </span> For Option C., divide 52 by 4, the quotient should be 13.
For Option D., 52 over 4 is another way to write 52 divided by 4, therefore, the answer, once again, is 13.
When comparing all the answers, you will notice all the answers are equal, except option B.
We take 2 marbles from 20 marbles and the total ways is 20x19:2=190 But we need only 2 red marbles and the ways is 14x13:2=91 And finally we do the division 91:190=91/190 is the probability we need
