There are 14+18 = 32 marbles that are either red or yellow.

This is out of 44 marbles total.

Divide the two values (32 and 44) to get: 32/44

Now reduce: 32/44 = 8/11

To reduce, I divided both parts by the GCF 4

The final answer as a fraction is 8/11

Use a calculator to find that 8/11 = 0.7273 approximately

The approximate answer in decimal form is 0.7273 (which represents roughly 72.73% probability)
