Question
The octonuts are a brave bund of underwater explores who rescues sea creatures. The number of sea creatures they rescue in a given week. In a bounded variable, R. Answer the question below using the following information about R: P(R lessthanorequalto 24) = 0.80 P(R lessthanorequalto 23) = 0.78 P(R lessthanorequalto 22) = 0.75 P(R lessthanorequalto 21) = 0.72 P(R lessthanorequalto 20) = 0.68 P(R lessthanorequalto 19) = 0.64 P(R lessthanorequalto 18) = 0.61 P(R lessthanorequalto 17) = 0.58 What isP(R greaterthanorequalto 20)?_____What is P(19 greaterthanorequalto R greaterthanorequalto 21)?______Explanation / Answer
P(R>=19)= 1 - P(R=<19)=1-0.64=0.36
P(19=<R=<21)=1-P(R>=P(R>=19)*P(R=<21)=0.36*0.72=0.259
