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
If you subtract the equation 8.0-8.2=-0.2. If you were to do the opposite then you would answer the equation 8.2-8.0=0.2. So therefore you have two options, -0.2 or 0.2. Good luck!
Answer:
$7.30
Step-by-step explanation:
The problem statement gives rise to two equations:
- 3a +2c = 33.50
- 1a +4c = 30.50
If we double the first equation and subtract the second, we have ...
2(3a +2c) -(1a +4c) = 2(33.50) -(30.50)
5a = 36.50 . . . . simplify
a = 7.30 . . . . . . .divide by 5
The cost of one adult ticket is $7.30.
