Answer:
0.938
Step-by-step explanation:
From the question :
p = 0.14
Number of children, n = 7
P(x ≤ 2) = P(2) + P(1) + P(0)
Using binomial probability :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
We could also use the binomial probability calculator :
P(x ≤ 2) = 0.3479 + 0.3965 + 0.1936
P(x ≤ 2) = 0.938

Answer:both 1 and 2 are correct
Step-by-step explanation:
All the names for the mathematical statement given as pi over 2 are π/2 rad and 90 degrees
<h3>How to determine all the names for pi over 2?</h3>
The mathematical statement is given as:
All names for pi over 2
Rewrite the mathematical statement as follows:
All names for pi/2
This can further be rewritten as:
All names for π/2
In the measurements of angles.
The value of π is 180 degrees
So, we have
π/2 = 180 degrees/2
Evaluate the quotient
π/2 = 90 degrees
Hence, all the names for the mathematical statement given as pi over 2 are π/2 rad and 90 degrees
