What is probability ?

Probability is the chance of occurring a certain event out of total possible events that can order in a given situation.

According to the given question an urn contains 19 red marbles, 29 blue marbles, and 43 yellow marbles.

So there are total of ( 19 + 29 + 43 ) = 85 marbles.

∴ No. of sample space N(s) = 85.

No. of red marble N(red) = 19.

One marble is to be chosen from the urn without looking the probability of choosing a red marble P(red) is N(red)/N(s) which is

P(red) = 19/85

P(red) = 1/5.
