Question

You roll a 6-sides die with faces number 1 through 6, and toss a coin. What is the probability of rolling a 2 or getting heads?

Answer 1

2/3

Explanation:

P1= rolling 2 = 1/6

P2 = heads = 1/2

P1 OR P2 = P1 + P2 = 1/6 + 1/2 = 4/6 = 2/3

Answer 2

Answer:Pr (A or B)= 2/3

Explanation:

Pr (rolling a 2) = 1/6.....let this be A

Pr (getting a head) =1/2.....let this be B

Pr (A or B) = 1/6 + 1/2

=4/6

Pr (A or B)= 2/3
