Answer:
0.54
Explanation:
A = "she's up all night 'til the sun"
B = "she's up all night for good fun"
P(A) = 0.29
P(B) = 0.27
P(A or B) = 0.02
The following relationship is known:

Therefore, applying the given data:

The probability that "she's up all night 'til the sun" AND "she's up all night for good fun" is 0.54.
