Answer:
B. 2/3
Step-by-step explanation:
To solve this we have to take into account this axioms:
- The total probability is always equal to 1.
- The probability of a randomly selected point being inside the circle is equal to one minus the probability of being outside the circle.
Then, if the probabilities are proportional to the area, we have 1/3 probability of selecting a point inside a circle and (1-1/3)=2/3 probability of selecting a point that is outside the circle.
Then, the probabilty that a random selected point inside the square (the total probability space) and outside the circle is 2/3.
Using a calculator, I arrived to answer C because if you enter it in right you arrive at 39.419, rounding it to 39.42
Answer:
Volume is the amount of 3-dimensional space an object occupies. Volume is measured in cubic units.
Step-by-step explanation:
Answer:
P(she selects the route of four specific capitals) = 1 in 2,686,320 or 3.72 x 10⁻⁷
Step-by-step explanation:
Assuming that the order at which she visits each of the four cities matters, the number of possible routes is the permutation of choosing 4 out of 42 capitals:
Therefore, the probability that she selects the route of four specific capitals is 1 in 2,686,320 or 3.72 x 10⁻⁷
