You are bidding on sixsix items available on an online shopping site. You think that for each bid you have a 2020% chance of winning it, and the outcomes of the sixsix bids are independent events. Let X denote the number of winning bids out of the sixsix items you bid on. Find the probabilities.

Title:

Step-by-step explanation:

There is a 20% chance of winning a bid.

Hence, the chance of losing a bid is (100 - 20) = 80%.

It is given that i have win in X bids out of total 6 bids.

I have loosed in (6 - X) bids.

Again, from 6 bids we can chose X bids in ways.

Hence, the required probability is .

y=1/4x-4

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
