The number of times that a person contracts a cold in a given year is a poisson random variable with parameter λ = 5. suppose that a new wonder drug (based on large quantities of vitamin c) has just been marketed that reduces the poisson parame- ter to λ = 3 for 75 percent of the population. for the other 25 percent of the population, the drug has no appreciable effect on colds. if an individ- ual tries the drug for a year and has 2 colds in that time, how likely is it that the drug is beneficial for him or her?

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
