• Since the product has to end in 1, 3, 7 or 9, the units place of all the 4 numbers we want to multiply can’t end in 0, 2, 4, 5, 6, 8. That means it can only end in 1, 3, 7, 9.<\/li>\n
• This means that the probability of selecting one number that ends in 1, 3, 7 or 9 is 4\/10 = 2\/5.<\/li>\n
• Therefore the probability of selecting four numbers that end in 1, 3, 7 or 9 is (2\/5) x (2\/5) x (2\/5) x (2\/5) = 16\/625.<\/li>\n
• Hence, the probability of selecting 4 numbers such that their product ends in 1, 3, 7 or 9 is 16\/625.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
