Answer:
a) get all heads= 0.0625
b) get at least one tail= 0.9375
Step-by-step explanation:
a. Probability of getting four heads 0.0625.
b. Probability of getting at least one Tail 0.9375.
a. Probability of getting four heads
Probability = (1/2)^4
Probability= 1/16
Probability= 0.0625
b. Probability of getting at least one Tail
A = Getting all four heads
B = Getting at least one tail
P(A) + P(B) = 1
P(B) = 1 - P(A)
Hence:
P(B) = 1 - 0.0625
P(B) = 0.9375
Inconclusion the Probability of getting four heads 0.0625 and the Probability of getting at least one Tail 0.9375.
