ANSWER

P(A\cap B)=0

EXPLANATION

If the two events are disjoint, then they are mutually exclusive.

This means that their intersection is zero.

Therefore

n(A\cap B)=0

This implies that,

P(A\cap B)= \frac{n(A\cap B)}{n(U)}

P(A\cap B)= \frac{0}{n(U)} = 0

The probability that the two events will occur together is 0, which means an impossibility.

Let's call the unknown amount of money <em>x</em>

Betty spend 5/12 of her money (5/12)x and had 42 dollars left. Translated,

x - \frac 5{12} x = 42

Solving,

x(1 - \frac 5{12}) = 42

\frac{7}{12} x = 42

x =  \dfrac{12}{7} \cdot 42 = 72

Answer: $72
