Answer:
0.156
Step-by-step explanation:
Using binomial probability formula, we have :
P( a out of n ) =ⁿCₐ x pᵃ x qⁿ⁻ᵃ ------------------------------------------------- (1)
Where n = total number of sample
a = number of success
p = probability of success
q = probability of failure
n-a = number of failures
From the question:
n =10 , a = 7, p=0.54, q = 1-p = 0.46
Substituting into equation (1) we have:
P (7 out of 10) = ¹⁰C₇ x (0.54)⁷x (0.46)¹⁰⁻⁷
= 0.1563
≈ 0.156
Answer:
12. 3:12
Step-by-step explanation:
that is 12
The midpoint is C, (-0.5,0.5)
Find the middle between the x and y coordinates and that is the midpoint
A) 45%, (100-200)/200=0.45 which also equals 45% :)
4 boys have brown hair because 1/2 of 24 is 12 and 1/3 of 12 is 4
