Using it's concept, it is found that there is a 0.04 = 4% experimental probability of rolling a 5 on the red number cube, NCI, and a 2 on the blue number cube, NC2.
A probability is given by the number of desired outcomes divided by the number of total outcomes.
In an experimental probability, these number of outcomes is taken from previous trials.
Researching this problem on the internet, it is found that out of the 250 rolls, 10 resulted in a 5 on NC1 and 2 on NC2, hence:
p = 10/250 = 1/25 = 0.04.
0.04 = 4% experimental probability of rolling a 5 on the red number cube, NCI, and a 2 on the blue number cube, NC2.
