Answer 1

Answer:

(d) is true

Explanation:

Given

$Brown = 8$

$Purple = 7$

Required

Which of the options is true

A) P(Brown) = P(Not Brown)

P(Brown) is calculated as:

$P(Brown)=\frac{Brown}{Brown + Purple}$

$P(Brown)=\frac{8}{8+7}$

$P(Brown)=\frac{8}{15}$

P(Not Brown) is calculated as:

$P(Not\ Brown) = 1 - P(Brown)$ --- Complement rule

$P(Not\ Brown) = 1 - \frac{8}{15}$

Solve

$P(Not\ Brown) = \frac{7}{15}$

Both are not equal.

Hence, (a) is not true

(b) P(Brown) < P(Not Brown)

In (a) above

$P(Brown)=\frac{8}{15}$

$P(Not\ Brown) = \frac{7}{15}$

By comparison;

$P(Brown) > P(Not\ Brown)$

Because:

$8/15 > 7/15$

Hence, (b) is not true

(c) P(Not Brown) > P(Brown)

This is the same as (b)

i.e. both conditions represent the same.

Hence, (c) is incorrect

(d) P(Brown) > P(Not Brown)

In (b), we established that

$P(Brown) > P(Not\ Brown)$

Because:

$P(Brown)=\frac{8}{15}$

$P(Not\ Brown) = \frac{7}{15}$

$8/15 > 7/15$

Hence, (d) is true
