Theoretical probability is what, theoretically, the probability <em>should </em>be, regardless of data. Because there are only two options, the probability for getting heads on each toss should be 50%. For the total thirty tosses, theoretically, the coin <em>should</em> land on heads fifteen times, or five per trial, which is determined solely on the number of options.
Experimental probability is what the probability was based on the given data. In the first trial, head was scored 5 times, or 5/10, or 50%. This was repeated in the second and third trials. So, based purely <em>on the data,</em> the probability of the coin landing on heads was also 50%.
I hope this helps!

Answer:
probability = 0.2517
Step-by-step explanation:
given data
boy kittens = 9
girl kittens = 6
choose kittens at random = 9
solution
total kitten are = 9 + 6 = 15
first we get here total no of probability that is
n(s) = 15 C 9
n(s) =
n(s) =5005
and
total way to chose 5 boy kittens is = 9 C 3
n(3) =
n(3) = 84
and
total way to chose 4 girl kittens is = 6 C 4
n(4) =
n(4) = 15
so
total way to chose 5 boy kittens and 4 girl kittens is
total way = 84 ×15 = 1260
so probability that the director chooses 5 boy kittens and 4 girl kittens is
probability =
probability = 0.2517
Answer:
4.3%
Step-by-step explanation:
Write out the formula for simple interest:
i = p r t, where i is the interest earned, p is the principal, r is the interest rate as a decimal fraction, and t is the elapsed time in years.
Here, this i = p r t becomes
$645 = $3000*r*(5 yr).
This is equivalent to:
$645 = $15000r.
Solving for r by dividing both sides of this equation by $15000, we get
$645
r = ------------ = 0.043
$15000
Thus, the correct answer is the first one: 4.3%
