Question

explain why the ratio x/1,200 equals the ratio 83/240

Answer 1

Step-by-step explanation:

It is given that in case of 240 trials 83 red cubes were drawn, therefore, the

experimental probability that a red cube is drawn was found to be

83

P(red)

240

Now, in case of 1200 trials, let x be the number of red cubes drawn, therefore,

the experimental probability that a red cube is drawn was found to be

х

P(red)

=

1200

Since the experimental probability remains the same or does not depends on

the number of trials or experiments, therefore, it can be used for prediction

of the number of red cubes drawn in 1200 trials. Thus, we can find the

value of x by equating experimental probability and solving the following

proportion.

х/1200

= 83 /240
