Calculating conditional probability

Complete Question

Calculating conditional probability

The usher at a wedding asked each of the 80 guests whether they were a friend of the bride or of the groom.

Here are the results:

Bride :29

Groom :30

BOTH : 20

Given that a randomly selected guest is a friend of the groom, find the probability they are a friend of the bride.

P (bride | groom)

Answer:

The probability is $P(B|G) = \frac{2}{3}$

Step-by-step explanation:

The sample size is $n = 80$

The friend of the groom are $G = 30$

The friend of the groom are $B = 29$

The friend of both bride and groom are $Z = 20$

The probability that a guest is a friend of the bride is mathematically represented as

$P(B) = \frac{29}{80}$

The probability that a guest is a friend of the groom is mathematically represented as

$P(G) = \frac{30}{80}$

The probability that a guest is both a friend of the bride and a friend of the groom is mathematically represented as

$P(B \ n \ G) = \frac{20}{80}$

Now

$P(B|G)$ is mathematically represented as

$P(B|G) = \frac{P(B \ n \ G)}{P(G)}$

Substituting values

$P(B|G) = \frac{\frac{20}{80} }{\frac{30}{80} }$

$P(B|G) = \frac{2}{3}$

Help me mathematics

Ede4ka [16]

Answer:AB=15 ,angle A=53.1°,angle B=36.9°

Step-by-step explanation:

AB=√(12^2+9^2)

AB=√(12x12+9x9)

AB=√(144+81)

AB=√(225)

AB=15

TanA=12/9

TanA=4/3

A=Tan(inverse)(4/3)

A=53.1° angle A=53.1°

angle B=180-(90+53.1)

angle B=180-143.1

angle B=36.9°
