What is the probability of obtaining a head and a six when a fair coin and and a die are tossed together? 

A.

\(\frac{1}{12}\)

B.

\(\frac{1}{3}\)

C.

\(\frac{1}{2}\)

D.

\(\frac{2}{3}\)

Correct answer is D

\(\text{p(a head and a six)} = \text{p(a head)} + \text{p(a six)}\)

= \(\frac{1}{2} + \frac{1}{6} = \frac{2}{3}\).

 

 

Hint: Probability of A and B occurring should be greater than probability A or B happening.
