Answer:

0.382

0.4

option (a)

Explanation:

Formula to calculate probability

a)

probability = number of times event occur / total number of trials

Experimental probability of landing on white = 191/500 = 0.382

b)

probability = favourable outcome / total outcome

Theoretical probability of landing on white = 2/5 = 0.4

c)

As more trials are conducted, the experimental probability generally gets closer to the theoretical probability.
