What is the probability of rolling a single die to the number 5 and simultaneously flipping a
penny to heads?
a) 1/6
b) 1/12
c) 1/3
d) 5/12

1/12  (Answer B)

Step-by-step explanation:

These constitute two separate and independent events.  The probability of rolling a 5 is 1/6, and that of flipping heads is 1/2.  We multiply these two probabilities together:

The probability of both happening together is thus (1/6)(1/2) = 1/12

the monthly balance will be $75,000
