This is approximately equal to 0.167

====================================================

Step-by-step explanation:

A = event of getting either a 1 or 2

P(A) = probability event A occurs

P(A) = 2/6 = 1/3, since there are two ways to get "1 or 2" out of six total

B = landing on heads

P(B) = 1/2, there are two sides and only one is heads

P(A and B) = probability getting a 1 or 2 and flipping heads on a coin

P(A and B) = P(A)*P(B) .... only possible if A and B are independent

P(A and B) = (1/3)*(1/2)

P(A and B) = (1*1)/(3*2)

P(A and B) = 1/6
