• A. $0.1136$
• B. $0.2176$
• C. $0.2273$
• D. $0.8091$

Answer 1

Answer: (C)

$0.2273$

Given data, major hurricanes of $1990-1999$ = $5+20$ =$25$
total number of hurricanes of $1990-1999$ = $44+66$ = $110$
portion of major hurricanes = $\frac{majorhurricanesof1990-1999}{totalnumberofhurricanesof1990-1999}$= $\frac{25}{110}$
= $0.2273$
