Question

1. in a lottery there are 44 balls.

7a what is the probability of a particular ball being drawn first?
probability = \\(\frac{1}{44}\\)
5 nailed it!
7b a ball is discarded after it has been drawn. if ball number 21 is drawn on the first go, what is the probability of ball number 10 being drawn next?
probability = \\(\frac{1}{43}\\)
5 great job!
7c is the probability of each successive ball drawn the same as the probability of the first ball drawn?
yes a no b

Explanation:

7c Solution:

Step1: Recall probability of first draw

The probability of the first ball (e.g., ball 21) being drawn was $\frac{1}{44}$.

Step2: Analyze successive draws

After the first draw, one ball is discarded, so the total number of balls left is $44 - 1 = 43$. For a successive draw (e.g., ball 10), the probability is $\frac{1}{43}$. Since $\frac{1}{44}
eq \frac{1}{43}$, the probabilities differ.

Answer:

B. No
