1. Four dice are rolled. What is the
dice3;4244, dice4;2444) = ⅙*⅙*⅙*1/6 =1/
proba- bility of getting exactly
1296
three "4's" and one "2" in any
use the addition rule to calculate the total
order?
prob- ability
Addition rule for total probability = (1/
1296) + (1/ 1296)+ (1/ 1296) + (1/ 1296)
= 4/1296
2. How many distinct ways can 2 people sit Distinct ways; means formulashort
(matters!!!! bc
in 5 chairs? distint means unique ways) 5!/
5-2! =20
3. A bag is filled with 20 pieces of Candy A Without replacement : means you will
have to
and 10 pieces of Candy B. If you choose subtract from n (grand total)
2 pieces of candy at random 20+10 = 30 grand
without replacement, what is the total P (candy A) =
probability of picking one piece of 20/30total
Candy A first and one piece of P(candy B) = 10/29new total
Candy B second? "And" = multiply probabilities
4. If Mark has 200 Facebook friends, what 1- P(none of birthdays 365 days)
is the probability that he shares the
same birthday with at least 1- (364/365)^200
one of them? Power up the # given (ex: 200)
5. The median of a set of 5 subtract
consecutive
integers is 9. What is the variance of the square
set?
add all and divide by total number of set
