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}\\) 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 = enter your next step here

Explanation:

Step1: Determine remaining balls

After drawing one ball (ball 21), the number of remaining balls is \( 44 - 1 = 43 \).

Step2: Calculate probability

The probability of drawing ball 10 next is the number of favorable outcomes (1, since there's one ball 10) divided by the number of possible outcomes (43 remaining balls). So the probability is \( \frac{1}{43} \).

Answer:

\(\frac{1}{43}\)
