Question

During a probability experiment, Jesse draws one marble each from two different jars and records the result. She then places the marbles back in their respective jars and repeats the experiment for a total of 10 trials. On her first trial, Jesse pulls a blue marble from the first far and a green marble from the second jar, and the results are indicated as BG. The results are shown in the table, where B stands for blue, G stands for green, and R stands for red. Trial 1 2 3 4 5 6 7 8 9 10 Result BG RB RR BG RG BB GG BR GB RR Based on the results in the table, what is the experimental probability of pulling a red marble from the first jar and a green marble from the second jar (RG) ? 1 A. 5 B. 1 6 Ос. 1 OD 1 1 10

Answer 1

SOLUTION AND EXPLANATION OF CONCEPT

From the table in the question, the result for Red in the first jar and green in the second trials (RG) occurs in the fifth trials

The formular for probability is give as

`Pr(E)=\frac{required\text{ outcome}}{total\text{ outcome}}`
`Pr(RG)=\frac{Number\text{ of trials for RG}}{Total\text{ number ot Trials}}=(1)/(10)`

Hence the probability of red in the fir
