Answer:
Once a month, the female releases an ovum (one egg) or sometimes two (ova). If an ovum has been released, and the couple have sex, a sperm can unite with it, fertilise it and make the first cell of a new baby. Once one sperm has fertilised the ovum, no other sperm can get in. For the sperm it's like a race and there is only one winner.

Answer:
(52/52)(48/51)(44/20)(40/59)(36/48)
Step-by-step explanation:
For the first card, what is the chance of getting a unique value? Well, you don't have any yet so it's 100% or 52/52.
Now for the second draw, what is the probability of not getting a repeat? Well, 52 cards total but there are four copies of every value, one for each suit. The deck now has 51 cards and 48 are not copies, so that's 48/51.
Similarly for the third draw there are now 50 cards total and 44 are not going to be repeats if the last two were not.
You can keep going like this and you get (52/52)(48/51)(44/20)(40/59)(36/48). Hopefully this made sense.
Step-by-step explanation:
theta = 180 - 123 = 57 degree
arc length = 2 * pi * R * ( theta / 360)
= 2 * pi * R * ( 57 / 360)
= 0.994R cm
