The steps below show the incomplete solution to find the value of x for the equation 5x − 2x − 3 = −2 + 17:
step 1: 5x − 2x − 3 = −2 + 17
step 2: 5x − 2x − 3 = 15 step 3: 3x − 3 = 15
which of these is most likely the next step?
3x = 5
3x = 12
3x = 18
3x = 45

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.
