2 answers:
The experimental probability that Hilda pulled a red marble is 0.11752 or 11.752%.
<h3>What is probability?</h3>Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.
For a class experiment, Hilda places different colored marbles in a bag. She pulls a marble at random from the bag, records its color, and then puts the marble back in the bag. She repeats this process 25 times.
The overall results are shown in the table.
Blue, Red, Yellow, Orange Frequency 6, 4, 8, 7 respectively.
P(red) will be 1/4 and P(not red) will be 3/4.
The number of trials (n) is 25.
Frequency of the red (r) = 4
Then the probability of getting red will be
The experimental probability that Hilda pulled a red marble is 0.11752 or 11.752%.

Answer:
C.
.
Step-by-step explanation:
Let r represent the cost of one packet of radish seeds and let t represent the cost of one packet of tomato seeds.
Roman spent $62.75
This implies that,
Roman bought 32 packets of seeds and one packet of radish seeds costs
$ 1.75.
One packet of tomato seeds costs $ 2.50.
This implies that,
Using guess and check means we substitute into the given equation.
