Rylie Mcclure · Answer 1

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

Step-by-step 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

Marc Grimes · Answer 2

2/3

Step-by-step explanation:

P1 = rolling 2 = 1/6

P2 = heads = 1/2

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