A clinical specialist is contemplating the spread of an infection in a populace of 1000 lab mice. During any week, there is a 80% likelihood that a contaminated mouse will defeat the infection, and during that very week there is a 10% likelihood that a noninfected mouse will get tainted. 300 mice are presently contaminated with the infection. What number of will be contaminated (a) one week from now and (b) in 3 weeks?

Every one of 13 fridges of a specific sort has been gotten back to a merchant on account of a perceptible, piercing, swaying commotion when the coolers are running. Assume that 10 of these coolers have a faulty blower and the other 3 have less significant issues. On the off chance that the fridges are analyzed in irregular request, let X be the number among the initial 9 inspected that have a blemished blower.

***Please tackle the two sections or don't endeavor this problem.***

(a) Calculate P(X 7). (Round your response to four decimal spots.)

(b) Determine the likelihood that X surpasses its mean worth by more than 1 standard deviation. (Round your response to four decimal spots.)

For a specific waterway, assume the dry season length Y is the quantity of continuous time spans in which the water supply stays under a basic worth y0 (a shortfall), went before by and followed by periods in which the stockpile surpasses this basic worth (an excess). An article proposes a mathematical dissemination with p = 0.397 for this irregular variable. (Round your responses to three decimal spots.)

***Please clarify the means and show what recipe is being used.***

(a) What is the likelihood that a dry spell keeps going precisely 3 spans?

(b) At most 3 stretches?

(c) What is the likelihood that the length of a dry spell surpasses its mean worth by in any event one standard deviation?

Every one of 13 coolers of a specific kind has been gotten back to a merchant due to a perceptible, sharp, swaying commotion when the fridges are running. Assume that 10 of these coolers have an imperfect blower and the other 3 have less significant issues. On the off chance that the coolers are inspected in arbitrary request, let X be the number among the initial 9 analyzed that have a faulty blower.

(a) Calculate P(X 7). (Round your response to four decimal spots.)

(b) Determine the likelihood that X surpasses its mean worth by more than 1 standard deviation. (Round your response to four decimal spots.)..
