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
5r=20 10p=100 14t=42
100+42+20=162
5r+10p+14t=$162
Answer:
The surface area of ball is 400π sq.cm
Answer:
201cm
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
the side Q-R corresponds to K-L
just as O-P corresponds to K-J
K-J= 36
O-P=6
36/6=6
so 24/6=4
