1. When rolling two fair, eight-sided dice, each with faces numbered 1 through 8, what is the probability that the two numbers rolled have a sum of 9? Express your answer as a common fraction.
2.What is the product of the GCF and the LCM of 48 and 72?
1. lets find the all the combination which sums up to 9.1+8,2+7,3+6.4+5,5+4,6+3,7+2,8+1 = 8 waystotal no. of combinations with two dice = 8*8 = 64so, probability of having sum of 9 = 8/64 = 1/8 (answer)
2. GCF of 48 and 72 is 24. LCM of 48 and 72 is 144so product of GCF and LCM = 24*144 = 24*144 (answer)Please best my answer and add me as your tutor so that I can help you further. Thanks :)
