URGENT Suppose that a law enforcement group studying traffic violations determines that the accompanying table describes the probability distribution for five randomly selected people, where x is the number that have received a speeding ticket in the last 2 years.

x
P(x)
0
0.08
1
0.31
2
0.25
3
0.18
4
0.10
5
0.08
Which of the following number of selected people having received a ticket would constitute an unusual event?

Just tell me how to set up the equation.

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.

What does independent variable and dependent variable mean in math?
