Question

19. Charlotte has a success rate of about 20%

Answer 1

Answer:

$P(x \ge 5) = 0.60$

Step-by-step explanation:

Given

$S = \{5, 2, 7, 2, 3, 4, 10, 6,4,6,3, 6, 6, 4, 8,5,7,7,1,5\}$

$n(S) = 20$

Required

$P(x \ge 5)$

First, we count the number of trials that are at least 5

$x = \{5, 7, 10, 6,6, 6, 6, 8,5,7,7,5\}$

So, we have:

$n(x \ge 5) = 12$

So, we have:

$P(x \ge 5) = \frac{n(x \ge 5)}{n(S)}$

This gives

$P(x \ge 5) = \frac{12}{20}$

$P(x \ge 5) = 0.60$
