Question

what is the probability of drawing 3 green marbles in a row with replacement?
0.0342
0.123
0.0189

Explanation:

1. Explanation:

• Step 1: Recall the formula for independent - event probability
• When events are independent (drawing with replacement makes the draws independent events), the probability of multiple independent events \(A\), \(B\), and \(C\) occurring is \(P(A\cap B\cap C)=P(A)\times P(B)\times P(C)\). Let the probability of drawing a green marble in a single draw be \(p\). Here, since we are drawing 3 green marbles in a row with replacement, the probability of the combined event is \(p\times p\times p = p^{3}\). But we are not given the value of \(p\) in the problem - so we assume we are supposed to check the given options. Let's assume the probability of drawing a green marble in a single draw is \(p\). If we assume that the probability of drawing a green marble in a single draw is \(p = 0.3\) (since \(0.3\times0.3\times0.3=0.027\) which is not among the options), if \(p = 0.123^{\frac{1}{3}}\approx0.497\) (not a common - sense probability value for a marble draw without more context), if \(p = 0.0189^{\frac{1}{3}}\approx0.266\), if \(p = 0.0342^{\frac{1}{3}}\approx0.325\). Without knowing the total number of marbles and the number of green marbles, we can't calculate the exact probability from first - principles. But if we assume that the problem is asking us to check which value can be the result of \(p^{3}\) for some valid \(p\) (where \(0\leq p\leq1\)).
• Let's check each option by taking the cube - root.
• For \(0.0342\), \(\sqrt[3]{0.0342}\approx0.325\).
• For \(0.123\), \(\sqrt[3]{0.123}\approx0.497\).
• For \(0.0189\), \(\sqrt[3]{0.0189}\approx0.266\).
• Since we don't have enough information to calculate the probability from the number of marbles, we assume we are just checking the form of the probability as a cube of a single - draw probability. A more reasonable probability value for a single draw of a green marble would be around \(0.325\) (since probabilities in such simple cases are usually not extremely large or small non - standard values). So we assume that the probability of drawing a green marble in a single draw \(p\) such that \(p^{3}=0.0342\).
