You are sending your friend a coded message by rearranging the letters in the word “strike.” that is, your code can be any arrangement of the letters in the word “strike” except one, “s-t-r-i-k-e.” how many different ways can you code your message? a) 720 b) 719 c) 120 d) 119

Option B) 719 ways

Step-by-step explanation:

Given that you are sending your friend a coded message by rearranging the letters in the word “STRIKE.” That is, your code can be any arrangement of the letters in the word “STRIKE” except one, “S-T-R-I-K-E.”

This means any code we can send using the given letters without strike.

There are 6 different letters and order matters for coding i.e. st is different from ts

Hence no of ways of arranging strike in different ways

We must subtract the arrangement strike from this as strike is not allowed.

Hence total number of different ways we code this message

=720-1 =719 ways

i think the answer is 90 hope this
