7
357 * 49 / 7 = 2499
there are 343 sevenths in 49 not 7 because it says sevenths not sevens.
49 metre because seven sevens = 49
7*7 + 7 - 7 is one of many ways to do this.
Answer 6Here is why:7x7=49 which is 1 too many, so there are six sevens in 48 with a remainder of 6.
42, 49, 56, 63, 70.....
there are four sevens in 28.
There are 12 sevens in 84.
There are 12 sevens in 84.
There are 13.714285 sevens in 96
There are 8 sevens in 56.
First, determine the probability of three sevens and two non-sevens, then worry about the permutations. The probability is the number of sevens, sevens minus one, sevens minus two, non-sevens, and non-sevens minus one; all over the number of cards left in the deck with each draw. The permutations of this configuration are 10 (you can verify this by arranging five cards as desired). P(exactly three sevens) = 10*(4/52)(3/51)(2/50)(48/49)(47/48) = (47)/(13*17*25*49) = 47/270,725 Those are pretty small odds, haha.
