The answer is 75%. This is because the 'or' rule for probability, the one we use when trying to determine P(A) or P(B), is to add the two probabilities. This means that we just need to add 30% and 45%, which gives us 75%.
I hope this helps!
It would be 270,725. The last choice.

+

First, find the least common denominator (LCD) of the two fractions.
Multiples of 16: 16
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16
The LCD is 16.
Second, make the denominators the same as the LCD. / Your problem should look like:

+
Third, simplify. The denominators are now the same. / Your problem should look like:

+
Fourth, join the denominators. / Your problem should look like:
Fifth, simplify. / Your problem should look like:
Sixth, convert to mixed fraction. / Your problem should look like:
