A couple decided to have 3 children B or G, the probability of a B P(B)= and P(G)=1/2

Find the probability that they have "At least one " girl.?

1. A dice is rolled 3 times, find the probability of getting "At least one" 6?
2. IN the Georgia Fantasy- 5 lottery , balls are numbered from 1 to 39, 5 balls are drawn randomly. To win the lotto you must mark 5 number from 1 to 39 on a ticket and your number must match the number on the 5 balls. What is the probability that you win?
3. If an operation can be performed in m ways, and a second operation can be performed in n ways. Then the total number of ways to perform the sequence of 2 operations is ----------------
4. The number of permutations of 6 objects is ----------------------------.

Define Binomial RDV X, what are the requirements for a Binomial Distribution of a DRV X, Binomial Probabilities of RDV X are computed by

P(X) - nCxp^xq^n-X

Define the term Poisson distribution of a RDV?

Under what conditions can you use Poisson distribution?

What is so special about Poisson distribution?

Can we use Poisson distribution for tossing a coin or rolling a dice or a lotto trial?

Fond the Poisson Probability and compute the me an muX and te standard deviation of the followings

Lambda L = 2 t= 5 Find P(5) and mux and Std. DevX ?

L= 0.5 t= 4 find P(4) and muX and Std DevX ?

L= 0.1 t= 10 find P( 2) and muX and Std. DevX ?

L = 1 t= 2 Find P(0) and muX and Std. DevX ?

L= 0.3 t= 8 find P( at least one) find mux and Std.devX?

L=0.3 t= 5 find P( fewer than 5) find muX and Std.DevX?
