The probability of randomly choosing a balloon that is either red or has polka dots will be 0.3077.
What is probability?
Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
Sarah has 52 balloons;13 of the balloons are red, and 4 of the balloons have polka dots.
Just 1 of the red balloons has polka dots.
Then the probability of randomly choosing a balloon that is either red or has polka dots will be
P = 13/52 + 4/52 - 1/52
P = (13 + 4 - 1) / 52
P = 16 / 52
P = 0.3077
