Question

So if there are 4 favorable outcomes out of 12 total outcomes, what is the P(rolling less than 5 and flipping heads)?


12


4


1/3


1/2

Answer 1

1/3

There are 6 die outcomes × 2 coin outcomes = 12 total. Favorable: 4 die results (<5) × 1 head = 4. So P = 4/12 = 1/3 (equivalently (4/6)·(1/2)).
