2-Digit Number is Multiple of 14Date: 9/10/96 at 17:40:9 From: Anonymous Subject: Probability that Multiple of 14... What is the probability that a randomly selected two-digit number is a multiple of 14? Date: 9/10/96 at 18:30:31 From: Doctor Tom Subject: Re: Probability that Multiple of 14... Well, the list of possible 2-digit numbers includes: 10, 11, 12, ..., 99 There are 90 of these. The multiples of 14 in this range include: 14, 28, 42, 56, 70, 84, 98 There are 7 of these. So there are 7 "successes" out of 90 possibilities, so the probability is 7/90. -Doctor Tom, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
