Issue 1: Assume the quantity of downloads each day of a famous APP A follows a typically dissemination with a mean of 2800 and standard deviation of 860. Answer the accompanying inquiries.

Expect the organization giving the downloading administration has planned its workers so there is likelihood 0.01 that the quantity of downloads in a day surpasses the workers' ability and more workers must be brought on the web.

Q:How many downloads each day are the workers intended to deal with?

1. Assume you're on a game show, and you're given the decision of three entryways: Behind one entryway is a vehicle; behind the others, goats. You pick an entryway, say entryway number 1 (however the entryway isn't opened), and the host, who can say for sure what's behind the entryways, opens another entryway, say entryway number 3, which has a goat. He at that point says to you, "Would you like to pick entryway Number 2?"

(a) What is the likelihood of winning in the event that you don't switch your decision?

(b) What is the likelihood of winning in the event that you do switch your decision?

(c) Is it for your potential benefit to switch your decision? (Type either yes or no)

2. Assume you're on an alternate game show. The host has you take a card from a deck of 52 playing a card game. You don't have the foggiest idea what card you picked on the grounds that it is face down. You're assume to figure the playing card you just picked. Suppose you surmise the two of clubs. The host at that point shows you the wide range of various cards in the deck aside from one card. Assuming he has the card you speculated, he doesn't show you that card. On the off chance that he doesn't have the card you speculated, he actually doesn't show you one card. He at that point says to you, "Do you need the card you initially picked or would you like to picked the card I have".

(a) What is the likelihood you speculated the card on the off chance that you don't switch your decision?

(b) What is the likelihood you speculated the card in the event that you do switch your decision?

(22)

(c) Is it for your potential benefit to switch your decision? (Type either yes or no)

Carriers at times overbook flights. Assume that for a plane with 50 seats, 55 travelers have tickets. Characterize the arbitrary variable Y as the quantity of tagged travelers who really appear for the flight. The likelihood mass capacity of Y shows up in the going with table.

y 45 46 47 48 49 50 51 52 53 54 55

p(y) 0.04 0.10 0.12 0.14 0.24 0.19 0.06 0.05 0.03 0.02 0.01

(a) If you are the main individual on the reserve list (which implies you will be the first to get on the plane if there are any seats accessible after completely tagged travelers have been obliged), what is the likelihood that you will actually want to take the flight?

(b) What is this likelihood in the event that you are the third individual on the reserve list?

A school tracks down that 8% of understudies have taken a distance learning class and that 20% of understudies are low maintenance understudies. Of the low maintenance understudies, 20% have taken a distance learning class. Let D = occasion that an understudy takes a distance learning class and E = occasion that an understudy is low maintenance understudy.

Section (a)

Discover P(D AND E).

Part (b)

Discover P(E | D).

Part (c)

Discover P(D OR E).

Part (e)

Are D and E totally unrelated? Clarify.

The occasions are not totally unrelated in light of the fact that

P(D AND E) 0.

The occasions are not fundamentally unrelated, which implies they can be added together, and the entirety isn't 0.2. The occasions are fundamentally unrelated in light of the fact that they are independent.The occasions are totally unrelated in light of the fact that

P(D AND E) = 0.
