Need help with probability questions i failed on my test.............
Q1: the game of two handed cribbage is played with a standard 52 card deck. Each player is dealt hands of 6 cards.
[a]. how many different 6 card hands could be dealt in euchre?
for this question i did 52 factorial divided by 46 factorial but got the answer wrong [pure guess]
is it 52! divided by (46!)(6!) ?
. In order to have the possibility of having the highest hand in cribbage you must be dealt three 5s and one Jack and two other cards. The other cards cannot contain a 5(but could be a Jack). How many possible 6 card hands could be dealt which would give you the possibility of getting a highest hand?
this question i have no clue..
[c]. What is the probability of being deal a hand with the possibility of being the highest hand?
this question i did p(a)=n(a)/n(s)
i subbed in 6 nor n(a), and 20358520 for n(s), and divided but got the answer wrong. I got the value for n(a) wrong, but the n(s) right
Q2:In a horse race you are told that the odds of winning for a certain horse is 3:2 (3wins : 2loses). What is the probability of winning?
this question i have no clue..
Q3: A garage door opener has 10 digits. 4 digits must be punched in sequence in order to open the door. It was noticed that 4 numbers on the pads were worn off more than the others. What is the probability of opening the garage door in one try if you know the 4 numbers but no in order?
for this question is it one divided by 4 factorial?
