Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
Answer:
Color : ___Green __yellow ___purple __ Grey
Prob : ____0.30 ___0.10 ______ 0.35 ___ 0.25
4 pins
Step-by-step explanation:
Color : ___Green __yellow ___purple __ Grey
Prob : ___. _______________ 0.35 ___ 0.25
P(green) = 3 * P(yellow)
ΣP = 1
Let
P(yellow) = x
P(green) = 3x
Hence,
x + 3x + 0.35 + 0.25 = 1
4x + 0.60 = 1
4x = 1 - 0.60
4x = 0.40
x = 0.4 / 4
x = 0.1
Hence,
P(yellow) = 0.1
P(green) = 0.1 * 3 = 0.3
Color : ___Green __yellow ___purple __ Grey
Prob : ____0.30 ___0.10 ______ 0.35 ___ 0.25
B)
If there are 14 pins in bag :
Number of green pins :
X * p(x)
14 * 0.3
= 4.2
= 4 pins
The probability of a foot of male being between 10 and 12. 5 inches is 59%.
<h3>Define the term normal distribution?</h3>
- The normal distribution approximates any real-valued random distribution which clusters around one single mean value.
- A cumulative frequency is a procedure that determines if the total amount of information in such a data set is less than and equal to a specific value.
The z score of the distribution is found as-
z = (x - μ)/σ
In which,
μ = mean = (11)
σ = standard distribution (1.5)
The likelihood that a male's foot measures between 10 and 12. 5 inches.
P(10 < x < 12.5)
For x = 10
z = (10 - 11) / 1.5
z = -0.67
check the p-value fro z score table.
p (z = -0.67) = 0.2514
For x = 12.5
z = (1.5 - 11)/1.5
z = 1
p (z = 1) = 0.8413
P(10 < x < 12.5) = 0.8413 - 0.2514
P(10 < x < 12.5) = 0.5899
P(10 < x < 12.5) = 58.99%
P(10 < x < 12.5) = 59%.
Thus, the likelihood of a male's foot being between 10 and 12. 5 inches is 59%.
