A student thinks that the regular pentagon in the diagram
Nadya [2.5K]

Answer:

A

Step-by-step explanation:

The student must have thought that every single arrowhead is a line of symmetry, so since there are 10 arrowheads, there must be 10 lines of symmetry. This is incorrect because if you look closely at the diagram, each line has 2 arrowheads, so the student is overcounting by a factor of 2. They should have just counted the number of lines, not arrowheads. Therefore, there must be 10/2 = 5 lines of symmetry, not 10. Hope this helps!

Harrizon [31]

Answer:

0.016

Step-by-step explanation:

To find the probability we have to Divide the number of events by the total number of possible outcomes. This will result in the probability of the single event.

Therefore, the formula of probability is

P(v) = \frac{no of events}{total possible outcomes}\\

In the given case,

P(v) = \frac{20}{1250}\\ P(v) = 0.016

Which is our required answer.
