4k(3c-10)
factoring:
14ck *2 + 10ck *2 - 16ck - 40k
28ck -16ck - 40k
12ck - 40k
the only thing you need to do is separate m:
2/7m= 3/14 + 1/7
2/7m= 5/14
m= (5/14)/(2/7)
m= 5/14 × 7/2
m= 35/28
m= 5/4
If the probability of an event is P, the probability of that event NOT happening is equal to 1-P:
Example: if you roll a six-sided dye, what the probability of getting 4.
==> P(4) = 1/6 & the probability of NOT GETTING 4 is P(NOT 4) =5/6
I could have written 1- 1/6 & you'll notice that 1-1/6 =5/6
The answer for this question would be 156
