### probability question

Out of 50 students, X=30, Y=15, making up 90% of the students. a) Tree diagram consists at the top of the 50 students, branching out to the second level 30, 15 and 5 for the three disciplines. The project team tree has three branches but, because students are randomly chosen, we cannot say wha

### Two dice are being thrown at once and getting three is considered a success. Obtain the probability distribution of the number of 3's.

The number of possible outcomes of throwing 2 dice together is 36, but only 2 of these outcomes add up to 3: 1+2 or 2+1. So the probability is 2/36=1/18. A probability distribution of all possibilities is given through the table below:  1+1=2 1+2=3 1+3=4 1+4=

### Does the distribution represent probability distribution X 1 2 3 4 5 P (x) 1/10 3/10 1/10 2/10 3/10

P(x) for x=2 appears to be a glitch in an otherwise ascending series of values. If, for example the P values were in order: 1/10, 2/10, 3/10, 3/10, 1/10, they could be a skew distribution. The usual form for a probability distribution is a rise to a summit value and then a falling off; or a cumulati

f(t) gives the probability as a point on a distribution curve while F(t) is the area beneath the distribution curve to the left of the point defined by f(t), representing the sum of the probabilities up to the point f(t). A typical example is a normal distribution curve (bell curve). Along the t

### What is the probability that a tree’s height exceeds the mean if normally distributed.

(a) 50% by definition of the mean as the central point of the distribution. (b) For Z=1 the table gives the value 0.8413 which is 0.3413 above 0.5000 (mean). So 34.13% is the probability of being in the range from the mean and 1 SD from the mean. 0.5000-0.3413=1-0.8413=0.1587 (15.87%) is the prob

### Poisson distribution question

The probability of no mail in a day when µ=10 and x=0 is P(10,0)=(e^-10)(10^0)/0!=e^-10=0.0000454 approx. This is 1/22026 approx., or an expectation of one day without mail in about 22,026 days. If we scale this up for 3000 days we get 3000*0.0000454=0.1362. So a new Poisson distribution

### statistics

(a)(1) The probability of a sale is 0.20 so the probability of no sale is 0.80. The probability of no sales with 8 firms is 0.80^8=16.78% approx. (2) We can use the binomial distribution with coefficients: 1 8 28 56 70 56 28 8 1. For no more than 2 sales we need the first 3 coefficients. (p+(p-1)

### How to plot

I guess you want to use Excel to plot a binomial distribution where the probability is p=0.25. Excel will plot a graph for non-cumulative and cumulative distribution. You use the BINOMDIST statistical function, which has 4 parameters:   number of successes (x axis); total number of trials,
