Events a and b are independent. find the missing probability.
p(b)= 9/20 , p(a and b) = 9/100, p(a)= ?
answer in decimal form rounded to one decimal place

Step-by-step explanation:

events A and B are independent:

P(A and B) = P(A)×P(B)

9/100= P(A)×9/20

P(A) = (9/100)/(9/20)

P(A) = (9/100) ×(20/9) =180/900

P(A) = 0.2

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.
