Answer:
<u>12 ways</u>
Step-by-step explanation:
The different ways to choose which three hamsters to put in the red cage.
At first , she must choose one of the two of the hamsters, Felix and Oscar, because they do not get along and cannot be in the same cage.
So, the number of ways to choose one of them = 2
Then she will choose 2 from the remaining 4 hamsters (order does not matter)
The number of ways to choose 2 from 4 = 4C2 = 6
So, the total number of ways = 2 * 6 = 12

Answer:
The number of pennies owned is 7 pennies
Step-by-step explanation:
The given parameters are;
The number of pennies left over when we break the pennies into groups of 2s = 1 penny
The number of pennies left over when we break the pennies into groups of 3s = 1 penny
Let the number of pennies owned = c
What we are given are as follows;
2 × a = c - 1
3 × b = c - 1
2 × a = 3 × b
a/b = 3/2
Therefore, if we multiply 2 by 3, and 3 by 2 we get 6
2 × 3 = 6, similarly 3 × 2 = 6
If we put 6 = c - 1, we get;
c = 6 + 1 = 7
c = 7
The number of pennies owned = 7 pennies.
See, to make a 5-letter word , 5 places are to be filled ___ ___ ___ ___ ___ 1st 2nd 3rd 4th 5th the first place can be filled in 5 ways (s,p,e,l,l) 2nd place in 4 ways. 3rd place in 3 ways. 4th place in 2 ways. 5th place in 1 way. now , ther are 2L's. hence total no. of words that can be formed=(5*4*3*2*1) / 2*1
