Answer:
23
Step-by-step explanation:
It is given that, in Russia there are 21 rocket launch failures out of 743 total launches. We need to find no of failures for the next 800 launches.
21 rocket = 743 launches
1 launch = 
For 800 launches,

or
= 23 failures
So, there are 23 failures in next 800 launches.
Permutation:
5! = 5 * 4 * 3 * 2 * 1 = 120
