Step-by-step explanation:
According to Reese's model, let the head of the coin represent male, and the tail represents female. The outcome can either be a male or a female.

pr(male) = 
pr(female) =
Therefore the probability of male equals the probability of females i.e .
Therefore,

Step-by-step explanation:
also, how many geometry worksheeta do u have, holy
it gives you the formula, so all you have to do is plug in the coordinates
If the track is 10km long, and X travels at 40 km/h, it will take 1 hour to do 4 laps. this means that car X will do one lap in 15 minutes. Y travels at 30 km/h, which means it will do 3 laps in 1 hour, meaning that car X will do 1 lap in 20 minutes.
X- 15, 30, 45, 60
Y-20, 40, 60
Therefore, after an hour, they will pass again.
