Find the number of letters from the word MAXIMUM where two consonants cannot occur. (Permutation)​
Hunter-Best [27]

Answer:

4!

Step-by-step explanation:

In word MAXIMUM, consonants are M & X. According to the question itself, consonants should not occur together.

So, we have to put vowels at each even position; only then the condition will be satisfied.

We can put this in 3! ways (permutations of A, I & U).  

For odd positions we can put 3-M's & a X. Total ways is 4!/3!   (as repetitions of M).

Hence, the answer is 4!/3! x 3! = 24 ways.  

24=4!.

Ms. Coleman's class has already collected 403 cans for a food drive, but the class wants to collect a total of at least 1,000 ca
pochemuha
We need to figure out how many more cans they need to bring.  We figure this out by subtracting 403 from 1,000, which gives us 596 more cans.  We now divide 596/28, to find how many each student would need to bring.  This equals 21.3.  You might want to mention that each student can't bring .3 of a can, so the answer could be 22 also.
