Let the no. be x
A/Q
=> 36 × x /100 = 18
=> x = 18 × 100 / 36
=> x = 50
3 : 5.....thats ur ratio...added = 8...so basically, Lisa wrapped 3 out of 8 (or 3/8) and Helen wrapped 5 out of 8 (or 5/8)
3/8(184) = 552/8 = 69 : Lisa wrapped 69
5/8(184) = 920/8 = 115 : Helen wrapped 115
Ok first do you know how to find the area or a triangle and a rectangle
There are 120 different possible groups.
(10 * 9 * 8)/(3 * 2 * 1) + 120
A. If the player chooses 6, 4, and 8 each time, they have 3/5 chances to win.
6+4= 10
6+8= 14
8+4= 12
These are all even so as long as they get one of these combinations they will win
b. All three combinations still work when multiplied
6*4=24
6*8=48
8*4= 32
