Answer:
30.87%
Step-by-step explanation:
Priya's simulation is fine, as 30% is represented by the 3 white cubes.
The more times the experiment is carried out, the closer it is to the theoretical probability, which is calculated as follows:
p (n = x) = nCx * p ^ x * q ^ (n-x)
We obtain that p = 0.3 and q = 1-0.3 = 0.7. also n = 5 and x = 2.
replacing we have:
p (5 = 2) = 5C2 * 0.3 ^ 2 * 0.7 ^ (5-2)
p (5 = 2) = 5! / (2! * 3!) * 0.03087
p (5 = 2) = 0.3087
which means that the probability is 30.87%, and the more the experiment is carried out, the closer it is to this probability.
