A bag contains red marbles and blue marbles.

If the probability of drawing a red marble is $\frac{21}{44}$2144, what is the probability of drawing a blue marble?

Consider this list of numbers:

$2,2,2,3,3,3,4,4,5,5,5,7,7,7,7,9,9$2,2,2,3,3,3,4,4,5,5,5,7,7,7,7,9,9

The probability of the local football team winning their grand final is $0.36$0.36.

The probability that it hails today is $0.43$0.43.

represents probabilities of simple and compound events
