please I need a readable answer and number associated with the question, apprentice it

What is the probability that a positive integer less than 20 picked at random has at least three prime factors? (The factors need not be distinct; for example, 8 has three prime factors, since 8 = 2 middot 2 middot 2.) Suppose that a fair die is rolled and a card is drawn from a standard deck of cards. What is the probability that the number shown on the die is the same as the number shown on the card (if any-note that only the numbers 2 through 10 are shown on cards, since aces, kings, queens, and jacks are represented by letters). What is the probability of getting exactly four heads when a fair coin in flipped eight times? A player in the Mega Millions lottery picks five different integers between 1 and 56, inclusive, and a sixth integer between 1 and 46, which may duplicate one of the earlier five integers. The player wins the jackpot if the first five numbers picked match the first five numbers drawn and the sixth number matches the sixth number drawn. a) What is the probability that a player wins the jackpot? b) What is the probability that a player wins $250,000, which is the prize for matching the first five numbers, but not the sixth number, drawn? c) What is the probability that a player wins $150 by matching exactly three of the first five numbers and the sixth number or by matching four of the first five numbers but not the sixth number? d) What is the probability that a player wins a prize, if a prize is given when the player matches at least three of the first five numbers or the last number
