Step-by-step explanation:
Answer:
The answer is 0.25
Step-by-step explanation:
This is a binomial distribution question, since it is equally likely probability of success (p) is 0.5 and the probability of failure (q) is 0.5.
Using binomial distribution formula
P(x) = n CX PX qn-x where C means combination
X =3 , n= 4
P(x) = 4c3 × (0.5) raise to power 3 ×(0.5) raise to power 1
P(x) = 4× 1/8 × 1/2
P(x)= 0.25
