f getting A head and a D A tail and either an A or a D.
1 answer:
Answer:
(Head and D) = 1/10
(Tails and A or D) = 1/5
Step-by-step explanation:
A coin has two sides so that a 50% chance that it will land on heads or tails
A pentagonal spinner has a 40% chance that it will land on D or A.
P (Heads) = 1/2
P (D)= 1/5
1/2 · 1/5 = 1/10
P (Heads and D) = 1/10
____________________________________________________________
P (Tails) = 1/2
P(A or D) = 2/5
1/2 · 2/5 = 1/5
P (Tails and A or D) = 1/5
