Answer:
The probability is 3/5
Step-by-step explanation:
A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
There are 2 + 4 + 4 + 4 + 2 + 4 = 20 itens.
Of those, 2 + 4 + 2 + 4 = 12 itens have white or red.
So
12/20 = 3/5
N equals <em>416</em>

your answer is going to be 2.22 or 0.002 i think .
The number of students with heights less than 163 cm should be expected is 12.
According to the statement
The mean of height is 175 cm
and the standard deviation of height is 6 cm.
We use normal distribution here with formula
Z= X - μ /σ
Here X is 167.5 and μ is 175 and σ is 6 cm.
Substitute the values in it then
Z = 167.5 - 175 / 6
Z = -1.25
-1.25 have a p value 0.012
Out of 1000 students:
0.012 x 1000 = 12.
So, The number of students with heights less than 163 cm should be expected is 12.
