If you flip a coin one time, the probability to get a Head is
p = 1/2
The probability of not getting a head in a single toss is :
q = 1 - 1/2 = 1/2
Thus there is only one unique situation to get the same number of heads and tails : in 10 toss you need to get exactly five heads, it will means that the rest is the tails.
Now using Binomial theorem of probability, the probability of getting exactly x = 5 heads in a total of n = 10 tosses is :
P(X = 5) = 
≈ 0.246
So the probability of that is 24,6 %
Good Luck

1) Zoe's town
April = 5 7/8 inches
May = 2 1/8 inches less than in April
5 7/8 ⇒ ((5*8)+7)/8 = 47/8
2 1/8 ⇒ ((2*8)+1)/8 = 17/8
47/8 - 17/8 = 30/8 ⇒ 3 6/8 ⇒ 3 3/4 inches rainfall in May.
April rainfall : 5 7/8 inches
May rainfall : 3 3/4 inches
Greatest Prime number less than 50 is 47. So, 47 students plus 3 teachers. There is a total of 50 people going on the trip.
