At Thomas Jefferson High School students are heavily involved in extra-curricular activities. Suppose that a student is to be selected at random from this school. Let the events A, M, and S be defined as follows, with the probabilities listed: A = student is active in the performing arts: P(A) = 0.20
M = student is active in vocal or instrumental music: P(M) = 0.32
S = student is active in sports: P(S) = 0.35 P(A intersection M) = 0.18; P(A intersection S) = 0.07; P(M | S) = 0.30
Calculate each of the following (show your work):
a. P(A|M)
b. P(A union M)
c. P(M intersection S)

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

b
