According to the general equation for conditional probability, if P(A upside down u B)= 5/7 and P(B)=7/8 , what is P(A|B)?

natta225 [31]

$P(A | B) = \frac{P(A \cap B)}{P(B)}$

$P(A|B) = \frac{5/7}{7/8}$

$P(A|B) = \frac{5}{7} \div \frac{7}{8}$

$P(A|B) = \frac{5}{7}\times\frac{8}{7}$

$P(A|B) = \frac{5*8}{7*7}$

$P(A|B) = \frac{40}{49}$

Let X be a normal random variable with mean 40 and standard deviation 2. Find P(X < 28).

Vikki [24]

Answer:

Step-by-step explanation:

Given :

Mean = 40 ; Standard deviation = 2

P(x < 28)

Obtain the Zscore :

Z = (x - mean) / standard deviation

P(Z < (28 - 40) / 2))

Z = (28 - 40) / 2

Z = - 12 / 2

Z = - 6

P(Z < - 6) = 0.000000
