A certain group of women has a 0.86​% rate of​ red/green color blindness. If a woman is randomly​ selected, what is the probabil
Mariana [72]

Answer:

The probability that a randomly selected woman has red/green color blindness is 0.9914

Step-by-step explanation:

Given that the proportion of women having red/green color blindness is 0.86%

Represent that with p

p= 0.86\%

Convert proportion from percentage to decimal;

p= \frac{0.86}{100}

p= 0.0086

In probability; opposite probabilities add up to 1;

Let the probability that a woman selected have red/green color blindness be represented with q;

p + q = 1

Subtract p from both sides

p - p + q = 1 - p

q = 1 - p

Substitute 0.0086 for p

q = 1 - 0.0086

q = 0.9914

<em>Hence, the probability that a randomly selected woman has red/green color blindness is 0.9914</em>
