Answer 1

Answer:

$P(x < 4) = \frac{9}{50}$

Step-by-step explanation:

Given

$n(S) = 50$

See attachment for distribution

Required

$P(x < 4)$

This is calculated as:

$P(x < 4) = \frac{n(1) + n(2) + n(3)}{n(S)}$

Using the data on the frequency distribution table, we have:

$P(x < 4) = \frac{4 + 2 + 3}{50}$

$P(x < 4) = \frac{9}{50}$
