1. A gambler in Las Vegas is cutting a deck of cards for $1,000. What is the probability that the card for the gambler will be the following?…
According to the information you provided, the probability of being struck by lighting is equal for the whole United States population. In this case, it will be 1/3000 or 0.00033333% . However, sometimes people can distort this probability by making themselves more probably being struck by lighting. For instance,people using phones on the road when it is storming or they stay in the trees when it is lighting. All these activities may increase the "true" risk probability and make it not "true" at all. Thus, I consider that probabilistic risk can be used to measure or estimate the level of risk when people are involved in certain activity but it is not completely "true" or…
Probabilities are computed or assessed in a number of ways. It depends upon what we are in fact considering. If we think about the games we played. Using the 1st game, coin flip, we have two possible results, a head or a tail. Therefore the possibility that a head or a tail comes is 50% or ½. When we have more than a single coin, in that case the probability of each side for each coin needs to be taken into account. If you continue to flip the coin more and more the chances that we get a fifty-fifty split becomes more likely. The total probabilities always add up to a total of 1. Next, let's think about the 2nd game which is the dice roll. In this case there are equal possibilities of all of the 6 sides. Therefore each side has got a probability of 1/6. I was a bit more confused with this however the more that I rolled the dice and watched the numbers change the more I saw what it was saying.…
In this lab, we’d learn about the likelihood that a particular event will occur is called probability. Every event happens independently. The probability of a coin flip has two possible outcomes: the coin may lands heads up or tails up. The probabilities of either outcome are equal. Therefore, the probability of a single coin flip will come up heads is one chance in two. This is 1/2, or 50 percent. In the first part, I toss a single coin for 20, 30, and 50 times. For the 20 tosses part, the observation is 10 heads-up and 10 tails-up, which is corresponding to the principle of probability: the chances of each situation are equal. For the 30…
