Answer:
78.5%
Step-by-step explanation:
The area of the square is equal to diameter squared
i.e 4 in × 4 in = 16 square inches
The area of the circle is π × r²
i.e π × 2² = 12.56637061
The percent of the time the point will be in the circle = (Area of the circle) ÷ (Area of the square) × 100
i.e × 100 = 78.53981631%
And is equal to 78.5% (rounded up to the nearest tenth of a percent)

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
Convert proportion from percentage to decimal;
In probability; opposite probabilities add up to 1;
Let the probability that a woman selected have red/green color blindness be represented with q;
Subtract p from both sides
Substitute 0.0086 for p
<em>Hence, the probability that a randomly selected woman has red/green color blindness is 0.9914</em>
