The probability is 0.69.
We find the z-scores that correspond with each end of the range we're looking for. To find a z-score, we use the formula:
Using a z-table (http://www.z-table.com) we see that the area under the curve left of the score 350 would be 0.228. The area under the curve left of the score 400 would be 0.918. To find just the range between 350 and 400, we subtract the area left of 350 from the area left of 400; this will give us just from 350 to 400:
0.918-0.228 = 0.69.

Answer:
The probability that the woman selected does not have red/green color blindness is 0.9945.
Step-by-step explanation:
Let <em>X</em> = a woman has red/green color blindness.
It is provided that, in a certain group of women the rate of red/green color blindness is <em>P</em> (<em>X</em>) = 0.0055.
A complement of an event <em>E</em>, is defined as the event of not <em>E</em>.
The probability of complement of an event <em>E</em> is:
Compute the probability that the woman selected does not have red/green color blindness as follows:
Thus, the probability of the complement of the event of a woman having red/green color blindness is 0.9945.
<h2>○=> <u>Correct option</u> :</h2>
<h3>○=> <u>Steps to derive correct option</u> :</h3>
Angle 1 and angle 3 are vertically opposite angles.
We know that :
▪︎ Vertically opposite angles are always equal.
Which means :
Angle 1 = Angle 3
Thus, the measure of angle 3 = 70°
▪︎Therefore, the correct option is (D) 70
