1/6
Step-by-step explanation:
- According to the question, the right combination of 2 wires cut (out of the 4 wires ) will defuse the bomb. To find all the possible combinations we using the following formulae;
nCr = n! / r! * (n - r)!
⁴₂C = 4! / 2! * (4-2)!
⁴₂C = 24 / 2 * 2
⁴₂C = 6
- There are a possible 6 combinations
- Therefore for probability of cutting the right combination of 2 wires is 1/6

Answer:
-4=x
Step-by-step explanation:
1) 1-2x=-x-3 (letter's to the left)
2) then you get 1-x=-3
3) then you subtract 1 on both sides
4) then you dived the -1
5)answer -4=x
140. If 150 in 1 case and double that is 300 for 2 cases which she uses everyday. 2 for everyday x a week is 7 x 2 = 14
