QUESTION 2. Find the number of possible choices for a 2-digit password that is greater than 19. Then find the number of possible choices for a 4-digit Personal Identification Number (PIN) if the digits cannot be repeated.

QUESTION 01. Two roads, Broadway and State, connect the towns of East-land and Harping. Three roads, Park, Fairvew, and Main, connect the towns of Harping and Johnstown. Find the number of possible routs from East-land to Johnstown that pass through Harping. Then find the probability that State and Fairvew will be used if a rout is selected at random. State the probability as a fraction and percent and its likelihood.

2. P(each girl chooses the same color)
3. P(two girls choose the same color, and the third chooses a different color)
4. P(each girl chooses a red sweater)

find the probability distribution for the number of fails that occur when 4 coins are tossed?
