Answer: P(B|G) = 3/5 = 0.6
the probability that the guest is the friend of bride, P(bride | groom) is 0.6
Complete Question:
The usher at a wedding asked each of the 80 guests whether they werea friend of the bride or of the groom. The results are: 59 for Bride, 50 for Groom, 30 for both. Given that the randomly chosen guest is the friend of groom, what is the probability that the guest is the friend of bride, P (bride | groom)
Step-by-step explanation:
The conditional probability P(B|G), which is the probability that a guest selected at random who is a friend of the groom is a friend of the bride can be written as;
P(B|G) = P(B∩G)/P(G)
P(G) the probability that a guest selected at random is a friend of the groom.
P(G) = number of groom's friends/total number of guests sample
P(G) = 50/80
P(B∩G) = the probability that a guest selected at random is a friend is a friend of both the bride and the groom.
P(B∩G) = number of guests that are friends of both/total number of sample guest
P(B∩G) = 30/80
Therefore,
P(B|G) = (30/80)/(50/80) = 30/50
P(B|G) = 3/5 = 0.6

Answer:
16/64 simplified to lowest terms is 1/4
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 16 and 64 is 16
Divide both the numerator and denominator by the GCD
16 ÷ 16
64 ÷ 16

Slope intercept form & in standard form , passes through (1, 7) , perpendicular to 3x + 7y = 1
Turn 3x + 7y = 1 into slope-intercept form.
Remember, slope-intercept form is : y=mx+b where m=slope & b=y-intercept.
To turn out given equation into slope-intercept form, we must get x & y onto different sides.
So, subtract 3x from both sides.
7y = -3x + 1
Then, divide both sides by 7.
y = -3/7x + 1/7
Remember, when an equation is perpendicular to another equation, both equations have negative reciprocals.
m₁=-3/7 & m₂=7/3
Our new equation has these things in it :
A slope of 7/3 & it passes through (1, 7)
So, simply plug these into the slope-intercept equation.
y=mx+b
y = 7/3x + 7 → (a)Slope-intercept form
Now we must put this into (b)standard form.
Standard form is : Ax+Bx=C
So, we just use our slope-intercept form, but rearrange it :)
y = 7/3x + 7
In standard form, x & y are on the same side, so we simply subtract 7/3x from both sides.
-7/3x + y = 7 → (b)Standard Form
