Answer:
Step-by-step explanation:
To convert square miles to square feet, multiply the square mile value by 27878400. For example, to convert 10 square miles to square feet, multiply 10 by 27878400, that makes 278784000 sq ft is 10 sq mi.
one+four+three=eight pens.
Two pens are selected without replacement.
Need probability of selecting two black pens.
Probability of selecting first black pen is four out of eight, 4/8
Probability of selecting second black pen is three remaining black pens out of the remaining 7 pens = 3/7
Probability of both events happening is the product of the two probabilities, according to the multiplication rule.
Therefore probability of selecting two black pens out of the initial eight pens
=(4/8)(3/7)=3/14=0.2143 (to the ten-thousandth).
Rounding to the hundredth will give you the required answer.
